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

purposeStoma outlet obstruction (SOO) is a notable complication following diverting loop ileostomy (DLI) for colorectal cancer. However, no definitive risk factors for SOO have been identified. This study aimed to determine the risk factors associated with SOO.

methodsThis retrospective study included 167 consecutive patients who underwent elective colorectal cancer surgery with DLI at Chiba University Hospital between January 2010 and October 2024. We evaluated the patient, tumor, and surgical factors along with the computed tomography-based anatomical measurements. These included rectus abdominis muscle (RAM) thickness, subcutaneous adipose tissue (SAT) thickness, stoma penetration angles, penetration site through the RAM, and proximal limb orientation measurements.

resultsSOO occurred in 21 (12.6%) patients. A univariate analysis demonstrated that central penetration of the RAM (P = 0.01) and caudal orientation of the proximal limb (P = 0.02) were significantly associated with SOO length. A multivariable logistic regression analysis indicated that stoma penetration through the central portion of the RAM was an independent risk factor for SOO (odds ratio, 3.38; 95% CI], 1.26-10.1; P = 0.02).

conclusionCentral RAM penetration was an independent risk factor for SOO. As the penetration site is a modifiable technical factor, avoiding the central RAM when creating the DLI may reduce the risk of SOO.
