Quality Assessment of Randomized Controlled Trials of Moxibustion Using STandards for Reporting Interventions in Clinical Trials of Moxibustion (STRICTOM) and Risk of Bias (ROB)

OBJECTIVES To assess the quality and completeness of published reports of randomized controlled trials (RCTs) of moxibustion. METHOD We searched six databases to retrieve eligible RCTs of moxibustion published from 2000 to December 2015. We used the STandards for Reporting Interventions in Clinical Trials of Moxibustion (STRICTOM) and Risk of Bias (ROB) tool to assess the completeness of reporting of RCTs of moxibustion and evaluate the reporting quality of included RCTs. RESULTS Thirty-four studies of moxibustion were analyzed using STRICTOM and ROB. Of the 34 studies, the completeness percentage of STRICTOM varied from 33% to 100% (mean 68%, median 67%). The completeness of STRICTOM items showed a rising tendency along with the publication year. The STRICTOM items of setting and context (14.7%), rationale for the control (17.6%), and response (26.4%) showed incomplete reporting. The number of RCTs that rated a low risk of bias for allocation concealment (n=6), blinding of participants and personnel (n=1), and blinding of outcome assessment (n=4) appeared to be small. CONCLUSION The quality of reporting of RCTs of moxibustion remains incomplete according to the STRICTOM and ROB tool at present. Researchers should consider the STRICTOM and ROB for improving not only the completeness of reporting but also the study design. General guidelines for RCTs of moxibustion are also required.
