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

backgroundWeight loss after sleeve gastrectomy (SG) demonstrates significant diversity in the long term and the implicated mechanisms behind suboptimal clinical response (SCR) or recurrent weight gain (RWG) need to be scrutinized. This study retrospectively examines weight-loss trajectories, aiming to identify critical time points to optimize follow-up strategies and guide future prospective research.

methodsThis is a single-center, retrospective study of 104 patients that underwent SG. Excess body weight loss (%EWL) was calculated at 1, 3, 6, 12, 24, 60, and at 160.4 ± 16 months, while RWG was defined as the difference between the body mass index (BMI) at evaluation and the minimum BMI achieved postoperatively. In accordance with the clinical response, patients were classified into good responders (Group A: %EWL ≥ 50 and RWG < 5 kg/m

resultsIn the first postoperative month good responders achieved the highest %EWL 24.4 ± 6.5, compared to the other two groups (p < 0.05). After 24 months, all patients showed a decrease in %EWL, with good and partial responders following the same pattern until the fifth year. After the fifth year, EWL% was significantly decreased in partial responders (p = 0.014), while in good responders it remained relatively unchanged (p = 0.159).

conclusionThe first postoperative month and the fifth postoperative year have been identified as potential critical periods for determining long-term clinical outcomes.
