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 determine the incidence of stoma-site incisional hernia (SSIH) after ileostomy reversal and identify the associated risk factors, focusing on fascial suture materials.

methodsThis single-center retrospective study included 194 patients who underwent ileostomy reversal for colorectal neoplasms (2010-2023) with ≥ 330 days of postoperative computed tomography follow-up. All fascial closures used interrupted absorbable sutures. SSIH was defined on computed tomography. Risk factors were evaluated using logistic regression, and inverse probability of treatment weighting (IPTW) was applied to assess the association between suture materials and SSIH.

resultsSSIH occurred in 21 patients (10.8%) at a median of 282 days, and five patients (23.8%) underwent hernia repair. In a multivariable analysis, higher body mass index (odds ratio [OR]: 1.24 per kg/m², p = 0.008) and use of braided absorbable sutures (OR: 2.90, p = 0.042) were associated with SSIH. IPTW analysis showed a consistent association with braided absorbable sutures (OR: 3.24, p = 0.013). In an exploratory model that included the calendar period, this association was attenuated.

conclusionsSSIH occurred in approximately 10% of patients after ileostomy reversal. A higher body mass index was consistently associated with SSIH. Fascial suture material may be a clinically relevant component of stoma-site closure; however, its independent effect requires further evaluation.
