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

purposeAnastomotic leakage (AL) after low anterior resection (LAR) for rectal cancer leads to significant postoperative morbidity and mortality. No studies have specifically addressed the impact of the Preoperative Stool Scale (PSS) for AL in rectal cancer surgery. The aim of this study was to assess the impact of PSS on AL in a cohort who underwent elective minimally invasive low anterior resection (mi-LAR) for rectal cancer.

methodsWe retrospectively reviewed 204 consecutive patients who underwent mi-LAR for rectal cancer from January 2018 and December 2024. The main outcomes measured were Grade ≥III AL and major morbidity.

resultsAL was identified in 4.4% of patients. Patients with a poor PSS were observed to have higher incidence of AL (22.7% vs. 2.3%), higher morbidity (36.3% vs. 8.2%) and longer hospital stay (22 vs. 15 days) in comparison to those with a good or excellent PSS. Univariate analyses showed that tumor stenosis, poor PSS, lower prognostic nutrition index, and larger tumor size were significantly associated with AL. A multivariate analysis revealed that a poor PSS was significantly correlated with AL (odds ratio [OR] 7.364, 95% confidence interval [95% CI] 1.532–35.391; p = 0.013).

conclusionsA poor PSS was found to significantly increase the risk of AL.
