Abstract

CONTEXT: Randomized controlled trials (RCTs) are important tools for evidence-based health care decisions. It is, therefore, important that they be conducted and reported with the highest possible standards. The aim of this study was to evaluate the reporting quality of the RCTs published in nephrology urology monthly journal and to examine whether there was a change over time in the reporting quality. EVIDENCE ACQUISITION: The quality of each report was assessed using the Consolidated Standards of Reporting Trials (CONSORT) 2010 Statement checklist and a 5-point quality assessment instrument, i.e. the Jadad scale. RESULTS: Eighteen (14 Iranian and 4 non-Iranian) RCTs were published from 2012 to 2014 on topics including renal stone (16.6), hemodialysis and transplantation (38.8), and prostate conditions (11.1). Interventions comprised surgery, drugs, and teaching method in 7 (38 ), 10 (55), and 1 (5) of them, respectively. According to the CONSORT checklist, the weakest reported items were registration number, identification as a randomized trial in the title, and settings and locations where the data were collected. The mean Jadad score of the reports was 2.72 +/- 1.36 (54 of their maximum possible total score). According to the Jadad and CONSORT scales, there was an increase in the quality of reporting from 2012 to 2014. CONCLUSIONS: This assessment shows low reporting quality scores in reports. Training courses for researchers, using standard reporting tools (e.g. CONSORT 2010 Statement checklist), and consultation with methodologists can improve the quality of published RCTs.
