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.

2 · The registry

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

introductionAlthough MBS is endorsed for eligible adolescents, the optimal age for intervention remains unknown. This study evaluates body mass index (BMI) and weight outcomes after sleeve gastrectomy (SG) in different adolescent age groups. MATERIAL AND

methodsA multi-institutional chart review was performed at three children’s hospitals in the United States, including patients who underwent SG from March 2013 to September 2024. Demographics, comorbidities, and pre- and post-operative weight and BMI were compared between three subsets: patients 11–14 years of age (“<15”), between 15 and 17.99 (“15–17”), and 18–23 (“18+”). The Kruskal–Wallis rank sum test and Pearson’s Chi-squared test were used.

resultsOf 324 patients, 55 were < 15, 168 were 15–17, and 101 were 18+. Mean BMIs at time of initial consultation were 45 ± 9, 48 ± 10, and 48 ± 8 respectively. There were no differences in gender, race, insurance type or comorbidities among groups. The youngest patients were more likely to gain weight from consultation to surgery (+ 7.6% BMI change compared to + 2% and + 1.2%, p < 0.001 in the intermediate and older groups, respectively). Day-of-surgery BMI was similar in all groups, as was %BMI change at 6 and 12 months postoperatively. Time from consultation to surgery was longest in the 18 + group (19 months) followed by < 15 (17 months) and 15–17 (13 months) (p = 0.003).

conclusionThe youngest cohort had significantly greater % BMI increase from consultation to surgery, with similar post-operative % BMI reductions. These findings suggest that earlier surgical intervention for pediatric patients may prevent additional preoperative weight gain and facilitate attainment of a healthy post-operative BMI.
