Metallic stent placement versus catheter drainage for malignant bilioenteric anastomotic stricture.
Article in Japanese journal of radiology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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 purpose of the study was to compare self-expandable metallic stent placement with catheter drainage for malignant bilioenteric anastomotic stricture in terms of efficacy and safety. MATERIALS AND
methodsThis study included 54 patients with malignant bilioenteric anastomotic stricture treated from March 2016 to February 2021. Twenty-seven patients underwent insertion of self-expandable metallic stent (Stent group); the remaining twenty-seven patients underwent internal-external catheter drainage (Catheter group). Technical success was defined as successful placement of stent or drainage catheter in the appropriate position; clinical success was defined as a 20% reduction in serum bilirubin within 1 week after the procedure, compared with baseline. Complications, duration to stent/catheter malfunction, and overall survival were evaluated.
resultsTechnical success was achieved in all patients in both groups. In the Stent group, 21 patients received one stent and the other 6 patients required two stents. Clinical success rates were similar between the groups [Stent group, 92.6% (25/27); Catheter group, 88.9% (24/27)]. There were no major complications. The median duration to stent/catheter malfunction was significantly longer in the Stent group (130 days) than in the Catheter group (82 days; P = 0.010). The median overall survival was also significantly longer in the Stent group (187 days) than in the Catheter group (118 days; P = 0.038).
conclusionSelf-expandable metallic stent placement might be better than internal-external catheter drainage for malignant bilioenteric anastomotic stricture in terms of the duration before stent/catheter malfunction and patient survival.
