1. Simple guidelines to do a
postgraduate research project
By Dr. Manori Gamage
Senior Lecturer
Department of Paediatrics
University of Sri Jayewardenepura.
2. Importance 0f a Research project during
Postgraduate training
It makes you to
• Learn basic research theory and techniques
• Understand how to do a literature search and a review
• Explore an area of interest
• Learn how to appraising everyday problems critically
• Acquire skills to communicate scientific research as verbal or written
presentations
3. Making a start on your project
• There are many steps as shown in figure 1
• Order is not necessarily fixed
• Choose the relevant steps according to the research type
• Additional tools are necessary to find and manipulate information
• Literature search through PubMed or Medline
• Analysis programmes like Microsoft Excel SPSS
4. An idea or problem
A clear research question Define objectives and hypotheses
Review of the relevant literature Learn about End-Note
A valid methodology to address the question
Metrics of measurement Data collection forms Ethics proposal Funding Engaging others
A spread sheet that reflects the data in the data collection form Gather the data/conduct the study
Develop an analysis plan Commence writing: intro/methods/dummy tables
Analysis and writing
Minor thesis/ publication

5. Choosing a research topic
• It starts with an
• idea that interests you
• A problem that you have noticed
• It should be feasible to finish between 6-12 months
• Get the assistance of your supervisors
• Identify a clear research question
• Choose a practical method
6. A clear research question
Most important component!!!
• Should be keeping with the interested theme
• Carefully selected with help of the supervisor
• Objective
• Answerable using the research method
9. Define :
P – Population
I – Intervention
C – Comparator
O – Outcome
T – Time
10. Methodology
Descriptive
Case Report Case series
Descriptive
Epidemiology
Analytical
Cohort studies
Case-control
studies
Case cross-
over studies
Cross sectional
studies
11. Study Design
• Depends on the research type
• Prevalence of the condition
• Short/Long term outcome
• Duration allocated for research
12. Plan data analysis
• Get to it before making the data collection tools
• Design data collection tools to answer specific research questions
• Include necessary questions in the most appropriate format
• Think and come to terms on statistical tests with the help of supervisors
• Design the database
• Easy to enter data
• Analyzable
• Reflects answers to research questions
• Start entering data to database early
• In quantitative research
• Be consistent with metrics
• Identify numerator and denominator
13. Ethics and Funding
• It is an enabler of good research in patient’s interest
• Mandatory for publication in a peer reviewed journal
• It is not usually required in systematic review of previous researches
• As a good doctor and a paediatrician, a researcher should adhere to ethical
principles
• Consent
• Autonomy
• Human dignity
• Confidentiality
• Non- maleficence
• Beneficence
• Justice
• Scientific integrity
14. Time management
• Do not leave project writing till the end
• Work steadily over the allocated time
• Start thesis writing early
• Expand the work that has been done on compiling the research
proposal
• Store all related data in a separate folder
• Refer back again if the data collection tool, database and thesis
provides answers to principal and supplementary research questions
• Balance your clinical and research training
• Keep yourself motivated and interested
15. Relationship with the supervisor
• Meet them regularly
• Keep them involved
• Seek help to solve any problem encountered during research
• Provide them with progress reports
16. Documents and backup
• Write one master document which can be used for initial proposal
• Expand it to form your thesis
• There can be multiple documents
• Abstratct
• Proposal
• Final report/ thesis
• Journal article
• Avoid ‘version confusion’ by keeping master document so that all
versions get updated at once
• Clearly label and date
17. • Ensure all agree on a system of version control
• Put date and initials of the person last edited the document
• Store all documents in a separate folder
• Back up all documents
• Either in a flash drive
• Or in a cloud storage e.g.: Google Drive, Dropbox
• Cloud storage enable sharing
• Flash drive should be protected by viruses
18. Writing style
• For the proposal ; use future tense
• In the thesis/report ; use past tense
• Language should be concise and clear
• A thesis should be written in a way that people without specific
knowledge can understand
19. Writing style
• For the proposal ; use future tense
• In the thesis/report ; use past tense
• Language should be concise and clear
• A thesis should be written in a way that people without specific
knowledge can understand
20. Thesis Structure
• There are many structures
• Can write with following components as chapters or subheadings of
one document
• Abstract
• Introduction
• Literature review
• Methodology
• Results
• Discussion
• Conclusions and recommendations
• references
21. Thesis Order and length
• No fixed order
• It could be anything from 4000-20000 words
• Can differ from the course that’s taken
• But its not the length that indicates the quality
22. Avoid plagiarism
• It is important that a thesis is writer’s/researcher’s own work
• Plagiarism is a form of cheating and is not accepted
• Can avoid this if everything that is written is writer’s own work
• Avoid copy-and-pasting
• Many universities use programmes like “Turnitin” and “Grammarly”
23. Components of a thesis
structure
A simple guide to write them
24. Abstract
• A very brief one page overview of the whole thesis
• 250-300 words
• In one to two sentences describe
⁻ Introduction
⁻ Method
⁻ Results
⁻ conclusions
25. Introduction
• 3-4 paragraph account
• Start with why it is an important topic to research
• Give contextual information on why the study was done
• Highlight the burden of the condition and its importance to the
specialty
• Point out if the topic was well studied or neglected
• Identify gaps
• State objectives and research questions
26. Literature review
• It is a summary of existing knowledge on the topic
• Relevant, concise and informative
• Should be focused on general and specific objectives
• State the search engines e.g.: PubMed, Google Scholar and key words
• Write from general to specific areas
• Instead of summarizing each individual research, tey to catagorise them
into themes and write
• If the literature on the subject is scanty, state it and point out the gaps
• Cite the references
27. Methodology
• It consist of how the study was done
• A researcher should be able to conduct the same research and
reproduce same/different results after reading the methodology
28. Study
population
Definitions of
terms
Plan of the
study
Data
collected
How, when,
where, how
often data
was collected
Data entry

database
Analytical
tests
Ethics
approval
Any
problems in
methodology
and they
were
addressed
29. Results
• Can be presented as narrative, tables, graphs and figures
• Results should be logical and organized
• Results should not be duplicated in each medium of presentation
• All the results should not be written as a narrative to prevent it being
too long and tedious
Only write the important results as a narrative
• Each table, figure or graph must be referenced in narration at the
appropriate place
• Results can be planned and written before the study is complete
using ‘dummy tables’
30. • There is no limit to number of tables
• In tables and the narrative include numbers and confidence intervals
together with percentages
• Accurately do the descriptive epidemiology using means, medians,
percentages, ranges, IQRs and confidence intervals
• Not all tables need a P value and not all P values <0.05 are significant
Avoid using P values to report minor post hoc results
• Describe the findings clearly, concisely in plain language
• Divide it to subheadings
• Give more importance to specific research question
31. Discussion
• It is an interpretation of the results
• Should refer to primary objectives and research questions and state
whether they have been achieved
• Organize discussion into thematic paragraphs/subheadings
• Allocate the first paragraph to restate main results in plain language
• Then compare and contrast the results with pre existing knowledge
• Beware not to duplicate the literature review
32. • Use appropriate language to show that you are scientifically open
• Avoid using unnecessary categorical or certain language
• Discuss the limitations of the study
• Identify biases and confounds
• Do not highlight post hoc P values
• Avoid making excuses
• Make sure no new results has been entered
33. Conclusions/Recommendations
• Should be brief
• State main findings related to main research question
• State if main objectives has been achieved
• State lessons learnt from study and how it should be applied
• Give recommendations
• Change of practice
• New policies
• Raised awareness
• State need for further research
34. References
• Any important fact stated in research should have a reference
• Applies usually to introduction, literature review and discussion
• Refer from original research paper
• Find the full article to make sure it implies the same p-oint yo6u’re
making
• Best way to cite references as numbers
• Use standard referencing methods
• E.g.: Harvard Referencing standard
• Applications like EndNote, Zotero, Mendelay
