1 · What the graph read from it

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.

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.

Abstract

objectivePreoperative weight changes, predictors of weight changes, and subsequent implications on postoperative BMI reduction in adolescents preparing for bariatric surgery (MBS) have not been well described.

methodsTeen-Longitudinal Assessment of Bariatric Surgery (Teen-LABS) consortium (prospective, observational MBS study at five centers from 2007 to 2011) participants who completed the preoperative phase within 3-9 months of initial visit were included in this analysis (n = 123). Participants were categorized into preoperative weight groups: > 1% loss, stable, or > 1% gain. Demographic, anthropometric, socioeconomic, medical, and behavioral data were analyzed. Postoperative percent BMI loss at 1, 5, and 8 years by weight group was compared.

resultsPreoperatively, 50% of participants lost weight, 20% remained stable, and 30% gained weight. The mean percent weight change by group was -4.2% (standard deviation [SD] 2.9%), +0.02% (SD 0.6%), and +5.2% (SD 5.3%), respectively. Eight-year postoperative BMI change was -21% (lost) and -26% (stable), compared to -15% among those who gained weight preoperatively (p = 0.11). No differences in preoperative weight-related behaviors were observed between groups.

conclusionsMost adolescents preparing for MBS maintained ±5% of their baseline weight. No statistically significant differences in postoperative BMI loss or factors predicting preoperative weight change were identified.
