Standards for reporting interventions in clinical trials of cupping (STRICTOC): extending the CONSORT statement.

Background: The standards for reporting interventions in clinical trials of cupping (STRICTOC), in the form of a checklist and explanations for users, were designed to improve reporting of cupping trials, particularly the interventions, and thereby facilitating their interpretation and replication.

Methods: A group of clinical experts, methodologists, epidemiologists, and editors has developed this STRICTOC checklist through a comprehensive process, including registration of this guideline, literature review, solicitation of comments, consensus meeting, revision, and finalization.

Results: The STRICTOC checklist includes 6 items and 16 sub-items, namely cupping rationale, details of cupping, treatment regimen, other components of treatment, treatment provider background, and control or comparator interventions. Illustrative examples of each item are also provided.

Conclusions: It is intended that the STRICTOC, in conjunction with both the main Consolidated Standards of Reporting Trials (CONSORT) Statement and extension for nonpharmacologic treatment, will raise the reporting quality of clinical trials of cupping.
