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

aimObesity has been reported to increase the risk of technical inability in performing ileal pouch-anal anastomosis (IPAA) in patients with ulcerative colitis (UC). This study aimed to prospectively investigate the association between visceral fat and the feasibility of pouch reach in hand-sewn IPAA.

methodsWe prospectively enrolled patients with UC scheduled for two-stage restorative proctocolectomy with a preoperative plan for hand-sewn IPAA. Patients were categorized into a conversion group that required conversion to stapled IPAA intraoperatively and a non-conversion group. Preoperative visceral fat area and anatomical indicators were measured using computed tomography (CT). Logistic regression analysis was performed to identify predictors of conversion surgery.

resultsA total of 106 patients were included, with 12 (11.3%) in the conversion group. Compared with those in the non-conversion group, patients in the conversion group had significantly higher body mass index (BMI), greater visceral fat, and a longer distance between the ileal end and the anal verge (p < 0.01). Logistic regression identified visceral fat (per 10 cm

conclusionsVisceral fat is an independent risk factor for conversion surgery in patients undergoing hand-sewn IPAA. Preoperative CT-based measurement of visceral fat may provide a more accurate prediction of pouch reachability than BMI alone. These findings may help surgeons decide preoperatively whether a hand-sewn IPAA is feasible.
