Assessment of Quality of Reporting in Randomized Controlled Trials of Moxibustion for Chronic Diseases Using the Consolidated Standards of Reporting Trials and Standards for Reporting Interventions in Clinical Trials of Moxibustion Statements

Abstract

Background: Moxibustion is clinically used for treating various chronic diseases; however, the reporting quality of current published RCTs of moxibustion is unclear. Objective: To assess the reporting quality of RCTs focusing on moxibustion as a treatment for chronic diseases. Methods: Seven databases were searched to identify relevant RCTs. Criteria for evaluating the reporting quality of standard RCT elements and moxibustion intervention-related information were developed based on the CONSORT statement and its STRICTOM extension, respectively. Multivariate regression models were used to investigate factors impacting reporting quality. Results: A total of 310 RCTs were included, with 41 (7.6%) published in English journals and 269 (92.4%) in Chinese journals. The median CONSORT and STRICTOM scores of these RCTs, with a maximum score of 100, were 41.2 and 62.9, respectively. RCTs with a later publication year and with protocol registration or ethical approval exhibited significantly higher CONSORT and STRICTOM scores. Higher CONSORT scores were also significantly associated with English-language publication, funding support, and inclusion of a safety evaluation, while higher STRICTOM scores were additionally associated with an active-control design. Conclusion: The reporting quality of RCTs focusing on moxibustion treatment for chronic diseases is subpar, with gradual but limited improvement over the last 25 years. To enhance the reporting quality of moxibustion RCTs, researchers should develop a comprehensive study protocol and standardize result reporting based on CONSORT and STRICTOM statements. Registration platforms, ethical approval organizations, funders, and journals can also contribute to this improvement by bolstering structured information reporting in the review process.
