    • Why to talk about Reporting? • A coming mandatory era • Help to make research in the world more organised • Sometimes good research may be undermined by poor reporting
    • What about Good reporting? • A Standarised way of reporting • Approved by authorised bodies
    • Equator
    • •CONSORT (RCT) •STROBE (observational) •STARD (Diagnosis) •PRISMA (SR)
    • Checklists
    • Other checklists: • Systematic review meta-analyses require a QUOROM (PRISMA) statement checklist : • Reports of observational studies in epidemiology require STROBE: • Meta-analysis of observational studies requires a MOOSE statement: http://www.consort- ent%202000.pdf • Manuscripts reporting results of evaluations of diagnostic tests require a STARD flow diagram and checklist :
    • How To Start? • Register ur trial • The Answer is : Number
    • Issued May 2005
    • Clinical trial registries • NIH - • WHO - • Meta-register of clinical trials:
    • rp/en/
    • How To Start? • For any clinical trial: A protocol should be written • It is essential for study conduct, review and reporting • The question is how to write a protocol • The Answer is : SPIRIT
    • SPIRIT (Standard Protocol Items: Recommendations for Interventional Trials) • is an international initiative that aims to improve the quality of clinical trial protocols by defining an evidence- based set of items to be addressed in a protocol.
    • STUDY PERIOD Enrolment Allocation Post-allocation Close-out TIMEPOINT** -t1 0 t1 t2 t3 t4 etc. tx ENROLMENT: Eligibility screen X Informed consent X [List other procedures] X Allocation X INTERVENTIONS: [Intervention A] [Intervention B] X X [List other study groups] ASSESSMENTS: [List baseline variables] X X [List outcome variables] X X etc. X [List other data variables] X X X X etc. X
    • BJOG requires: • A flowchart/checklist • A copy of the ethics approval (or an explanation as to why ethics approval was not received) • A copy of the original protocol upon which the trial was based • Proof of registration – after 1st July 2005 this must have been prospective (The trial registration number should be included at the end of the abstract)
    • What Are the Secrets of Reporting? • Submission – Talk the paper up a little in the covering letter – Attention to details such as section numbers, equations, notation, etc. – Put as much effort into the revision as the original submission
    • Revision Secrets • Don’t ignore the reviewers or editor no matter how stupid they are • Repeat the reviewer comments then respond to them • Highlighten ur revision statements
    • Back to reporting • Register your study (trial) prospectively • Follow reporting guidelines (Equator) • Clear concise manuscript
    • Don’t give up
