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

purposeWe evaluated ultrasound-guided manual reduction as an initial management strategy for incarcerated obturator hernia, both as a bridge to elective surgery and as a pragmatic non-operative option in severely frail patients.

methodsWe retrospectively analyzed consecutive patients who underwent attempted manual reduction for incarcerated obturator hernia between 2012 and 2025, excluding those with suspected bowel necrosis. The reduction success, associated factors, and subsequent outcomes were assessed.

resultsManual reduction was successful in 39/46 lesions (84.8%) without procedure-related complications. Early presentation tended to be associated with successful reduction (median 12 vs. 48 h, p = 0.057). Compared with emergency surgery after failed reduction (n = 7), elective surgery following successful reduction (n = 24) was associated with lower bowel resection rates (0% vs. 42.9%, p = 0.008), higher mesh use (100% vs. 57.1%, p = 0.008), and a shorter postoperative stay (4 vs. 12 days, p = 0.002). Among the eight severely frail patients managed non-operatively, seven (87.5%) met the predefined clinical endpoints.

conclusionUltrasound-guided manual reduction appears to be feasible in selected patients with incarcerated obturator hernia, serving as a bridge to elective mesh repair under favorable conditions. In carefully selected severely frail individuals, it may also represent a pragmatic non-operative management option.
