6.  In 1993, 30 experts comprised of medical journal editors, clinical trialists, epidemiologists, and methodologists met in Ottawa, Canada with the aim of developing a new scale to assess the quality of randomized controlled trial (RCT) reports  One outcome of the meeting was the Standardized Reporting of Trials (SORT) statement.This statement consisted of a 32-item checklist and flow diagram in which investigators were encouraged to report on the various aspects of how RCTs were conducted.

7.  Concurrently, and independently, another group of experts, the Asilomar Working Group on Recommendations for Reporting of Clinical Trials in the Biomedical Literature, convened in Asilomar (California), USA, were working on a similar mandate  At the suggestion of Drummond Rennie, Deputy Editor of JAMA, representatives from both groups met in 1996, in Chicago, USA.. The meeting resulted in the Consolidated Standards of Reporting Trials (CONSORT) Statement, which was first published in 1996

8.  PRISMA for systematic reviews of randomized trials; MOOSE for systematic reviews of observational studies; STARD for diagnostic accuracy studies; REMARK for tumor marker prognostic studies; TREND for non- randomized evaluations of behavioural and public health interventions; STROBE for observational studies.PRISMAMOOSESTARDREMARKTREND STROBE

9.  Consolidated Standards of Reporting Trials, encompasses various initiatives developed by the CONSORT Group to alleviate the problems arising from inadequate reporting of randomized controlled trials (RCTs).

10.  The CONSORT Statement comprises a 25-item checklist and a flow diagram, along with some brief descriptive text. The checklist items focus on reporting how the trial was designed, analyzed, and interpreted; the flow diagram displays the progress of all participants through the trial. checklistflow diagram

22.  Item 9 - Mechanism used to implement the random allocation sequence (such as sequentially numbered containers), describing any steps taken to conceal the sequence until interventions were assigned  Item 10 - Who generated the allocation sequence, who enrolled participants, and who assigned participants to interventions  Item 9 - Mechanism used to implement the random allocation sequence (such as sequentially numbered containers), describing any steps taken to conceal the sequence until interventions were assigned  Item 10 - Who generated the allocation sequence, who enrolled participants, and who assigned participants to interventions

23.  Item 11a - If done, who was blinded after assignment to interventions (for example, participants, care providers, those assessing outcomes) and how

24.  Participants  Providers  Raters/data collectors  Data analysts

25.  The term “blinding” or “masking” refers to withholding information about the assigned interventions from people involved in the trial who may potentially be influenced by this knowledge.  Blinding is an important safeguard against bias, particularly when assessing subjective outcomes

26.  Item 11b - If relevant, description of the similarity of interventions
