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

BACKGROUND AND

aimsSelf-expandable metal stents (SEMS) are effective in alleviating malignant colorectal obstruction. However, bowel perforation following SEMS placement remains a significant concern, as it can adversely affect oncological outcomes. This study aimed to evaluate the recurrence and overall survival rates associated with SEMS-related bowel perforations.

methodsThis multicenter, retrospective analysis included patients with obstructive colorectal cancer who underwent SEMS placement as a bridge to surgery. The data collection period spanned from January 2008 to May 2019, with patient matching in a 1:5 ratio based on age, sex, tumor location, pathological stage, and achievement of curative resection.

resultsAmong the 412 patients who received SEMS placement, 25 (6.1%) patients experienced SEMS-related perforations (perforation group), with 21 instances classified as overt and four as silent perforations. Compared with 125 matched controls (non-perforation group), the perforation group showed elevated rates of emergent surgery, open surgery, and stoma formation, as well as a reduced interval from SEMS placement to surgery. The 5-year recurrence rate was notably higher in the perforation group than in the no-perforation group (47.4% vs. 21.5%, p < 0.001), whereas the 5-year survival rate was not significantly different between groups (63.8% vs. 80.0%, p = 0.330).

conclusionsSEMS-related perforation led to less favorable surgical outcomes and a higher rate of recurrence, although no notable impact on overall survival was observed. Considering the risk of perforation, these findings support the cautious use of SEMS as a bridge to surgery.
