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

The effectiveness of gastrointestinal bypass surgery for treating non-strangulated adhesive small bowel obstruction (ASBO) remains unclear. We aimed to compare the outcomes of gastrointestinal bypass and conventional surgery in patients with non-strangulated ASBO who were unresponsive to conservative treatment. The patients (n = 55) were divided into a bypass group (n = 15) undergoing bypass surgery and a non-bypass group (n = 40) undergoing conventional surgery, including adhesiolysis or small bowel resection. The serum albumin levels and prognostic nutritional index were comparable between the two groups at 12 months postoperatively. No patients (0%) in the bypass group and 13 (32.5%) in the non-bypass group experienced recurrent ASBO after surgery (p = 0.008). The recurrence-free survival was significantly longer in the bypass group than in the non-bypass group (p = 0.030). Gastrointestinal bypass surgery may reduce long-term recurrence and thus represents a promising alternative surgical strategy for non-strangulated ASBO.
