Presented at the 7th International Conference on Qualitative and Quantitative Methods in Libraries, Paris France. Application for the 'best fit' framework synthesis methodology to systematic review data extraction
The document discusses the importance of data extraction in systematic reviews and provides guidance on developing effective data extraction forms and processes. Specifically, it outlines that data extraction 1) involves accurately summarizing studies in a common format to facilitate analysis and presentation, 2) identifies numerical data for meta-analyses, and 3) obtains information to assess risk of bias and applicability; and recommends 4) developing structured yet adaptable forms, 5) providing clear instructions, and 6) considering single versus double extraction.
The document discusses evidence tables used in systematic reviews. It states that evidence tables should be established at the beginning of a project and not changed based on results. When two reviewers record different information in a field, a third reviewer should adjudicate to resolve discrepancies. Evidence tables are an important part of accurately conveying the results of a review and proper construction and data abstraction are crucial.

A systematic review is a comprehensive literature review designed to answer a specific clinical question using a pre-defined protocol. It requires at least 12 months to conduct due to extensive searches of published and unpublished studies, validity assessments of included studies, data collection, analysis, and keeping the review up-to-date. In contrast, a traditional literature review does not follow a pre-specified protocol or aim to be comprehensive. Systematic reviews also publish detailed search strategies to allow replication and apply statistical methods like meta-analysis to synthesized data from included studies.
An analytic framework is used in systematic reviews to:
1) Provide clinical and health services context for the mechanisms being studied and identify relevant evidence and populations.
2) Identify logical flaws in key questions as they are developed.
3) Be developed during the topic refinement process and used throughout the review to structure the analysis and report.
Using Investigative Analytics to Speed New Drugs to MarketCognizant
Investigative analytics can help speed up clinical trials and bring new drugs to market faster. It does this by improving data quality monitoring during trials. Exploratory data analysis and inferential statistics are two types of analysis that can be used to identify data quality issues. Exploratory analysis uses techniques like outlier analysis and repeated value analysis to detect anomalies in the data. Inferential statistics helps confirm findings and identify which sites require auditing. Together these methods provide a more cost-effective way to ensure data integrity and compliance during clinical trials.

In this presentation, Principal Statistical Scientist Ben Vaughn explains how clinical trial data moves from collection in the case report form to its presentation to FDA.
Observational studies should always be considered for inclusion in comparative effectiveness reviews. When deciding whether to include observational studies to assess benefits, reviewers should first determine if there are gaps in evidence from randomized controlled trials. When assessing harms, cohort and case-control studies should be routinely included. If gaps in trial evidence are identified, the review questions should be refocused to those gaps and observational studies addressing them should be included. Studies with high risk of confounding by indication bias are generally not suitable.
Leveraging Oracle's Life Sciences Data Hub to Enable Dynamic Cross-Study Anal...Perficient
This document discusses leveraging Oracle's Life Sciences Data Hub to enable dynamic cross-study analysis. It provides an overview of dynamic analytics and a systematic four-stage approach: 1) data preparation, 2) data selection and exploration, 3) model building and analytics, and 4) deployment and reuse. Key aspects of each stage are described, including conforming data, interactively subsetting data, selecting and building analytical models, and creating reusable analysis components. The proposed environment incorporates the Oracle Life Sciences Data Hub, SAS, and other tools. BioPharm Services are also briefly described to support integration and analytics.
The aim of this paper is to use Text mining(TM) concepts in the field of Health care System. We no that now days decision making in health care involves number of opinions given by the group of medical experts for specific disease in the form of decisions which will be presented in medical database in the form of text. These decisions are then mined from database with the help of Data Mining techniques. Text document clustering is considered as tool for performing information based operations. For clustering normally K-means clustering technique is used. In this paper we use Bisecting K-means clustering technique and it is better compared to traditional K-means technique. The objective is to study the revealed
groupings of similar opinion-types associated with the likelihood of physicians and medical experts.
The observation method is the most commonly used method for behavioral science studies. It involves direct observation by the investigator without asking questions to respondents. This allows the investigator to obtain information about current behaviors. It is less demanding than interview or questionnaire methods as it does not require active cooperation from respondents. Some common observation techniques include warranty cards, pantry audits, and distributor audits.
Meta-analysis is defined as quantitatively combining and integrating the findings of multiple research studies on a particular topic. It was coined by Glass in 1976 and refers to analyzing the results of several studies that address a shared research hypothesis. The key steps in a meta-analysis involve defining a hypothesis, locating relevant studies, inputting empirical data, calculating an overall effect size by standardizing statistics, and analyzing any moderating variables if heterogeneity exists. An example provided is a meta-analysis on coping behaviors of cancer patients that would statistically analyze results from quantitative studies with similar age groups.

Classification Scoring for Cleaning Inconsistent Survey DataCSCJournals
Data engineers are often asked to detect and resolve inconsistencies within data sets. For some data sources with problems, there is no option to ask for corrections or updates, and the processing steps must do their best with the values in hand. Such circumstances arise in processing survey data, in constructing knowledge bases or data warehouses [1] and in using some public or open data sets.
The goal of data cleaning, sometimes called data editing or integrity checking, is to improve the accuracy of each data record and by extension the quality of the data set as a whole. Generally, this is accomplished through deterministic processes that recode specific data points according to static rules based entirely on data from within the individual record. This traditional method works well for many purposes. However, when high levels of inconsistency exist within an individual respondent's data, classification scoring may provide better results.
Classification scoring is a two-stage process that makes use of information from more than the individual data record. In the first stage, population data is used to define a model, and in the second stage the model is applied to the individual record. The author and colleagues turned to a classification scoring method to resolve inconsistencies in a key value from a recent health survey. Drawing records from a pool of about 11,000 survey respondents for use in training, we defined a model and used it to classify the vital status of the survey subject, since in the case of proxy surveys, the subject of the study may be a different person from the respondent. The scoring model was tested on the next several months' receipts and then applied on a flow basis during the remainder of data collection to the scanned and interpreted forms for a total of 18,841 unique survey subjects. Classification results were confirmed through external means to further validate the approach. This paper provides methodology and algorithmic details and suggests when this type of cleaning process may be useful.
1) The study aimed to evaluate changes over time in the number of systematic reviews published in Japan and other countries.
2) It searched the MEDLINE database via PubMed for systematic reviews published between 2006-2015, filtering for country and year.
3) The results showed that the number of systematic reviews published annually increased worldwide and in most countries, though Japan published fewer than other countries. The number of reviews from the US may be overestimated.

Exploring the value of journal club participation using a hermeneutic dialect...Andrea Miller-Nesbitt
This document summarizes a study that used a hermeneutic dialectic process to understand the value of participating in journal clubs from the perspectives of academic librarians. The researchers interviewed 19 librarians about their experiences in journal clubs. They identified individual impacts like building knowledge and research skills. Group impacts included developing a research culture and spurring collaboration. Impacts on users included new services and more capable librarians. The hermeneutic dialectic process allowed the researchers to gather diverse views and construct a picture of journal club participation's impact.
This document provides guidance on developing a search strategy for a systematic literature review. It discusses clarifying the research question, identifying keywords and synonyms, using MeSH/subject headings, applying Boolean logic and truncation. The example search strategy provided searches PubMed for studies on the effectiveness of staying active versus bed rest for managing back pain. It combines terms for back pain, spinal diseases, and activities of daily living using Boolean logic. The strategy limits to clinical trials in humans and excludes animal studies.
The document summarizes the Data Extraction By Example (DEByE) approach for extracting semi-structured data from web sources based on user-provided examples. DEByE uses examples to generate extraction patterns for identifying objects in new documents. It presents a graphical user interface for specifying example objects and an extractor module that applies the patterns to new pages to populate a nested table structure. Experimental results found the bottom-up extraction strategy, which assembles objects from extracted attribute-value pairs, was effective at extracting most objects from sources with just a few provided examples.
In this presentation, Principal Statistical Scientist Ben Vaughn explains how clinical trial data moves from collection in the case report form to its presentation to FDA.

Quantitative critical appraisal october 2015Isla Kuhn
This document provides an introduction to critical appraisal of research articles. It explains that critical appraisal assesses the validity, results, and relevance of studies. Key aspects include evaluating study design, interpreting basic statistics and event rates, and determining applicability of results. Ready-made checklists can help appraise different types of research studies. Understanding concepts like confidence intervals, p-values, and risk ratios is important for interpretation. Practice is needed to develop critical appraisal skills.
This document outlines the key components of a literature review, including an introduction defining a literature review and its importance. It then lists and briefly describes the main sections of a literature review, such as different types of literature reviews, important considerations before writing one, strategies for writing it, and tips for writing it. Finally, it provides examples of references used in literature reviews.
This workshop is meant to be an introduction to the systematic review process. Further information about systematic reviews was available through a research guide. http://libguides.ucalgary.ca/content.php?pid=593664
The document summarizes presentations from three perspectives on progress towards open and interoperable research data service workflows:
1) Angus Whyte of the Digital Curation Centre discussed new DCC guidance and design principles for integrating research data service workflows.
2) Rory Macneil of Research Space discussed integrating their ELN with University of Edinburgh's DataShare and Harvard's Dataverse repositories using open standards.
3) Stuart Lewis of University of Edinburgh discussed their DataVault prototype for packaging data to be archived from a Jisc Research Data Spring project. The case studies illustrate challenges and opportunities for improving integration between active data management and long-term preservation services.

A Standardized Case Study Framework and Methodology to Identify quot Best Pr...Carrie Tran
This document proposes a standardized framework and methodology for conducting facility case studies. It argues that a consistent approach is needed to systematically compare facilities and identify best practices. A six-step process is outlined that includes defining the purpose and collecting data on design attributes and performance outcomes. The goal is to develop a facility database and inform design guidelines based on measurable outcomes from case studies. Conducting post-occupancy evaluations is presented as important for linking design decisions to outcomes. A standardized approach could allow for identifying exemplar facilities and determining evidence-based best practices.
A systematic literature review is a formal methodology to systematically identify and evaluate relevant research on a topic. It involves developing a review protocol and search strategy, screening studies for inclusion, assessing study quality, extracting data, and synthesizing findings. The process is more rigorous than a narrative review and aims to minimize bias by being comprehensive and transparent. Key aspects of the systematic review process include developing review questions, searching literature databases and other sources, selecting studies using inclusion/exclusion criteria, assessing study quality, extracting relevant data, and synthesizing the results.
1. Metrics are being developed to track downloads and reuse of research data to understand impact and reassure researchers. A new service called IRUS for Data will provide metrics for data repositories across different platforms.
2. There is debate around what data citations mean and how they should be used and understood. Projects are working to develop best practices and encourage responsible use of citation metrics for data.
3. Ensuring research data sharing is recognized in existing systems like journal policies is challenging due to lack of standards. Initiatives are working with publishers and repositories to develop guidance and implement principles for data citation.
This document discusses qualitative data analysis and representation. It begins by outlining ethical considerations and general steps to analysis, including preparing, reducing, and representing data. Common data analysis strategies are described, such as those from Madison, Huberman & Miles, and Wolcott. The data analysis spiral process is explained through collecting, analyzing and reporting data in an iterative process. Specific analysis procedures are covered for each qualitative approach, including managing data, coding, developing themes, interpreting findings, and visualizing results. Computer programs that can assist with analysis are also reviewed.
This document provides an overview of mixed methods research. It defines mixed methods research as combining both quantitative and qualitative research approaches in a single study. The key points covered include:
- Mixed methods allows researchers to collect both closed-ended quantitative data and open-ended qualitative data.
- Data can be mixed concurrently by collecting both types at the same time or sequentially by collecting one type of data before the other.
- Common mixed methods research designs include triangulation, embedded, explanatory sequential, and exploratory sequential designs.
- Issues like contradictory findings, bias, and sampling need to be considered depending on the specific mixed methods design used.
- The purpose of mixed methods research is that the combination of
The ability to understand a user’s underlying needs is critical for conversational systems, especially with limited input from users in a conversation. Thus, in such a domain, Asking Clarification Questions (ACQs) to reveal users’ true intent from their queries or utterances arise as an essential task. However, it is noticeable that a key limitation of the existing ACQs studies is their incomparability, from inconsistent use of data, distinct experimental setups and evaluation strategies. Therefore, in this paper, to assist the development of ACQs techniques, we comprehensively analyse the current ACQs research status, which offers a detailed comparison of publicly available datasets, and discusses the applied evaluation metrics, joined with benchmarks for multiple ACQs-related tasks. In particular, given a thorough analysis of the ACQs task, we discuss a number of corresponding research directions for the investigation of ACQs as well as the development of conversational systems.
