Traditional Chinese Medicine Interventions for Overweight and Obesity in Adults: An Umbrella Review and Evidence Map
By Qin Q, Gou Y, Xie Y and 2 others.
Abstract
Background
Traditional Chinese medicine (TCM) is widely used for weight management, but the reliability and comparability of the available review-level evidence remain uncertain. This umbrella review evaluated the methodological quality, certainty, and quantitative findings of systematic reviews and meta-analyses of TCM interventions for adults with overweight or obesity.
Methods
We searched PubMed, Embase, the Cochrane Library, CNKI, Wanfang, CBM, and VIP for systematic reviews and meta-analyses of randomized controlled trials. Methodological quality and certainty of evidence were evaluated using AMSTAR-2 and GRADE. Primary-study overlap was assessed using a citation matrix and the corrected covered area (CCA). Mean differences (MDs) were pooled only when outcome units were clinically compatible; standardized effects were reported narratively and were not combined with MDs. Random-effects models and leave-one-out analyses were used for body weight and body mass index (BMI).
