Energy balance
Both FDA-approved gastric balloon systems (gas-filled IGB and fluid-filled IGB) had the same effectiveness in terms of percent total body weight loss at balloon removal.
Both balloon systems can be considered equally effective for weight loss.
StrongSupportsmedium confidence
There were no differences in percent total body weight loss at balloon removal and 12 months between the balloon systems ( P =0.39).
Why this rating
Based on the retrospective cohort study design.
