Compared with non-surgical treatment of obesity , bariatric surgery leads to greater body weight loss and higher remission rates of type 2 diabetes and metabolic syndrome .
OBJECTIVE To quantify the overall effects of bariatric surgery compared with non-surgical treatment for obesity .
Quality of reporting in randomized trials published in high-quality surgical journals.
BACKGROUND R and omized controlled trials ( RCTs ) in surgery can provide valuable evidence of the efficacy of interventions if they are well- design ed , appropriately executed , and adequately reported . Adequate reporting of methodology in surgical RCTs is known to be poor , and adverse-event reporting in surgical research is inconsistent . The Consoli date d St and ards of Reporting Trials ( CONSORT ) statement is a framework to help authors report their findings in a transparent manner . Extensions to the CONSORT statement have been published recently to address deficiencies in adverse-event reporting and in reporting of specific criteria related to nonpharmacologic treatments . The aim of this study was to assess the quality of reporting of trial methodology and adverse events in a sample of general surgical RCTs published in high- quality surgical journals using the criteria specified in the CONSORT statements . STUDY DESIGN We used impact factor to identify the top three ranked surgical journals in 2004 . We then obtained information on all RCTs published in these journals in the 2005 calendar year . We assessed quality of reporting using Jadad score , compared the quality of RCTs from CONSORT-endorsing journals with nonendorsers , and assessed the number of RCTs adequately reporting key generic method ologic , adverse-event-related , and specific nonpharmacologic criteria . RESULTS Of 42 RCTs analyzed , only 40 % ( 17 of 42 ) had a Jadad score > or = 3 . There was no significant difference in the number of high- quality RCTs published in CONSORT-endorsing journals compared with nonendorsers ( p = 0.3 ) . The median percentage of RCTs adequately reporting generic method ologic , adverse-event-related , and specific nonpharmacologic criteria was 32.5 % , 17 % , and 36.5 % , respectively . CONCLUSIONS Quality of reporting of generic method ologic , adverse-event-related , and specific nonpharmacologic criteria in surgical RCTs is poor . Increased attention to quality of reporting of surgical RCTs is required if studies are to meet published criteria
