Registration of trials

•     JMPCC follows ICMJE policy: clinical trials must be registered in a WHO ICTRP Primary Registry or ClinicalTrials.gov before the first participant is enrolled.

•     Trials conducted in India must be registered with the Clinical Trials Registry – India (CTRI).

•     This includes trials of anaesthetic drugs and techniques, regional blocks, airway devices, ventilation strategies, fluids, sedation protocols, nursing and rehabilitation interventions, and quality-improvement interventions that assign patients or units to an intervention to study a health outcome.

•     The registry name and number must appear at the end of the abstract. The primary outcome reported must match the registered primary outcome; any change must be explained.

•     Retrospectively registered trials are considered only exceptionally, with the reason stated in the article.

•     Trial reports must include a data sharing statement.

Clinical reporting standards

•     Use standard, cited outcome definitions (for example, European Perioperative Clinical Outcome definitions, KDIGO criteria for AKI, Sepsis-3, the Berlin definition or its successor for ARDS, CAM-ICU for delirium).

•     Report drug doses, routes, timing and infusion rates in full; state when a drug is used outside its approved indication.

•     Report ventilator settings, fluid volumes and vasopressor doses with units.

•     Report adverse events and harms for all interventional studies.
