Clinical Trial Registration

The publication of results of all randomized control trials will only be considered if the ICMJE recommendations are followed. A trial registration number will have to be provided with the manuscript and should be mentioned after the end of the abstract. The trial should have been registered prospectively. Retrospective registration will not be considered. If the Trial was conducted without registration, the article will not be accepted for processing.

The ICMJE defines a clinical trial as “any research project that prospectively assigns people or a group of people to an intervention, with or without concurrent comparison or control groups, to study the cause-and-effect relationship between a health-related intervention and a health outcome. Health-related interventions are those used to modify a biomedical or health-related outcome; examples include drugs, surgical procedures, devices, behavioural treatments, educational programs, dietary interventions, quality improvement interventions, and process-of-care changes. Health outcomes are any biomedical or health-related measures obtained in patients or participants, including pharmacokinetic measures and adverse events.
