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 placement of self-expandable metallic stents as a bridge to surgery in malignant colon obstruction is concerning due to the long-term oncological results reported in recent published studies. The aim of this study was to evaluate the oncological consequences of stent-related perforations in patients with malignant colon obstruction and potentially curable disease.

methodsMEDLINE, Cochrane Library, Ovid and ISRCTN Registry were searched, with no restrictions. We performed five meta-analyses to estimate the pooled effect sizes by using a random-effect model. The outcomes were global, locoregional and systemic recurrence rate and 3 and 5 year-survival rate depending on the presence or absence of stent-related perforation.

resultsThirteen studies (950 patients) were included. The overall rate of stent-related perforation was 8.9%. The global recurrence rate was significantly higher in stent-related perforation group (41.2 vs. 30.8%; OR 1.70; 95%CI: 1.02-2.84; p = 0.04). Locoregional recurrence rate was higher in the perforated group than in the non-perforated group (26.6 vs. 12.5%), with statistically significant differences (OR 2.41; 95% CI:1.33-4.34; p = 0.004). No significant differences were found in systemic recurrence rate (13.6 vs. 20.5%; OR 0.77; 95%CI: 0.35-1.7; p = 0.51); 3-year overall survival rate (65.4 vs. 74.8%; OR 0.63; 95% CI:0.29-1.39; p = 0.25) and 5-year overall survival rate (48.3 vs. 58.6%; OR 0.67; 95%CI: 0.27-1.65; p = 0.38).

conclusionStent-related perforation is associated with an increased risk of global and locoregional recurrence. The successful placement of the stent as a bridge to surgery in the curative purpose of patients with obstructed colon cancer does not exclude the presence of underlying perforation, with the consequent danger of disease spread. PROSPERO registration number: CRD42020152817.
