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

purposeThe efficacy of laparoscopic surgery for left-sided colon cancer requiring splenic flexure mobilization is still unknown. This study investigates the risk factors for severe postoperative complications in patients undergoing laparoscopic left colectomy.

methodsThe subjects of this retrospective study were 353 consecutive patients who underwent laparoscopic left colectomy across seven participating hospitals between January, 2016 and December, 2024. Patients were divided into two groups according to the development of postoperative complications (POCs): a POC group (n = 70) and a non-POC group (n = 283). Severe POCs developed in 25 patients.

resultsThe POC group included more female patients (71.4% vs. 51.6%, p = 0.003), more patients with poor performance status (p = 0.005), more patients with combined resection of adjacent organ (14.3% vs. 4.6%, p = 0.006), and more patients with distant metastases (22.9% vs. 10.6%, p = 0.002). The hospital stay was also significantly longer for the POC group patients (18 days vs. 11 days, p < 0.001). Multivariate analysis for severe complications identified that blood loss greater than 50 mL (odds ratio [OR] 2.820, 95% confidence interval [CI] 1.195–6.654; p = 0.017) and distant metastases (OR 2.671, 95%CI 1.021–6.987; p = 0.045) were independent predictors of severe POCs.

conclusionsBlood loss and distant metastases were risk factors for severe POCs after laparoscopic left colectomy.
