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

purposePostoperative anal dilation after surgery for Hirschsprung disease (HD) still remains common practice. This study aimed to evaluate the benefit of routine dilations compared with a single postoperative calibration.

methodsPatients who underwent HD surgery within the first year of life at the University Children’s Hospital Zurich or the University Hospital Frankfurt were retrospectively reviewed. Two groups were compared: those with serial postoperative dilations (PD) and those with a single calibration (PC). Primary outcomes included anastomotic stricture, Hirschsprung-associated enterocolitis (HAEC), and constipation/fecal incontinence.

resultsA total of 91 patients were included—46 (51%) in the PD group and 45 (49%) in the PC group. Strictures occurred in 5 patients (10.9%) with PD and 9 (20%) with PC (p = 0.259). HAEC developed in 5 (10.9%) PD and 6 (13.3%) PC patients (p = 0.718). Rates of constipation/fecal incontinence were similar (p = 0.67).

conclusionRoutine postoperative anal dilation after HD surgery does not significantly reduce the incidence of strictures, HAEC, or constipation/fecal incontinence. Single postoperative calibration appears sufficient to determine whether further dilation is necessary.
