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

purposeTo describe institutional approaches to prophylactic appendectomy during Ladd's procedure in Japan, including rationales and prespecified exceptions.

methodsWe conducted a cross-sectional questionnaire survey through the Japanese Society of Pediatric Surgeons Under-45 Working Group. Member institutions reported their usual institutional approach in a standardized index scenario of emergency Ladd's procedure for midgut volvulus in a stable term neonate without intestinal necrosis or perforation. Responses were analyzed descriptively.

resultsForty-six of 50 invited institutions responded; 45 with a unified institutional approach were analyzed. In the index scenario, 22 institutions (48.9%) reported routinely performing prophylactic appendectomy and 23 (51.1%) reported not performing it. Performance institutions most commonly cited avoidance of future diagnostic confusion (72.7%) and prevention of future appendicitis (68.2%), whereas non-performance institutions emphasized confidence in contemporary imaging (60.9%) and avoidance of unnecessary procedures or complications (47.8%). Among performance institutions, omission was mainly reported in the presence of intestinal necrosis, perforation, or very or extremely low birthweight; deviations from non-performance were rare.

conclusionJapanese institutions show highly standardized yet divergent approaches to prophylactic appendectomy during Ladd's procedure. These findings clarify how diagnostic, operative, and future reconstructive considerations are balanced and provide a practical framework for protocol review and outcome-focused studies.
