Spin in the Scientific Literature on Bariatric Endoscopy: a Systematic Review of Randomized Controlled Trials

Obes Surg. 2022 Feb;32(2):503-511. doi: 10.1007/s11695-021-05790-3. Epub 2021 Nov 16.

Abstract

Bariatric endoscopy (BE) is an emerging treatment option for people with obesity. Spin (i.e., the practice of frequent misrepresentation or overinterpretation of study findings) may lead to imbalanced and unjustified optimism in the interpretation of the results. The aim of this systematic review was to determine the frequency and type of spin in randomized controlled trials (RCTs) of endoscopic primary weight loss techniques with statistically significant and nonsignificant primary outcomes. In conclusion, spin is observed in the abstract and main text of BE reports and can lead to misinterpretation or overinterpretation of the results. Since BE challenges the available non-endoscopic treatments for obesity, further research is needed to better qualify these techniques, as being effective and safe, as well as predefined hypotheses and analyses.
