Emotional and External Eating Behaviors Associated with Fat-Free Mass Loss Following Sleeve Gastrectomy.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundRapid weight loss after metabolic bariatric surgery may lead to excessive fat-free mass (FFM) loss, potentially reducing the procedure's health benefits. This study aimed to investigate the association between eating behaviors and FFM loss as well as total weight loss (TWL) at midterm (about 2-4 years) following sleeve gastrectomy (SG).
methodsThis cross-sectional study included 146 adults assessed approximately 2-4 years post-SG. Eating behaviors were evaluated using the Dutch Eating Behavior Questionnaire. The proportion of FFM loss relative to TWL (%FFML) was calculated, with excessive FFM loss defined as the highest tertile of %FFML (≥ 28%). The associations between eating behaviors and %FFML and %TWL were analyzed using linear regression models. Logistic regression was employed to estimate the odds ratios (95% confidence intervals (CIs)) for excessive FFM loss and suboptimal clinical response (TWL < 20%).
resultsThe mean time since SG was 30.8 ± 6.5 months, and 77.4% of participants were women. In the multivariable-adjusted model, emotional eating (B = 1.71; 95% CI 0.17, 3.25) and external eating (B = 1.76; 95% CI 0.01, 3.51) were associated with higher %FFML. The adjusted odds ratio (95% CI) for excessive FFM loss per unit increase was 2.28 (1.41, 3.70) for emotional eating and 1.84 (1.08, 3.15) for external eating. Eating behaviors were not significantly associated with %TWL or suboptimal clinical response.
conclusionsEmotional and external eating behaviors were independently associated with greater proportional FFM loss and increased odds of excessive FFM loss at midterm post-SG, though they were not linked to %TWL.
