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
Background and Aims: Postcholecystectomy bile duct strictures are currently managed by using multiple plastic stents. The use of metallic stents has been considered a contraindication due to fear that the metallic stent could block one of the main hepatic ducts. This study is the first to assess the use of an intraductal, fully covered metallic stent in postcholecystectomy strictures, including those with close proximity to the hepatic hilum. Methods: This study was a retrospective analysis of 11 patients who underwent insertion of an intraductal metallic stent for the management of postcholecystectomy strictures. In those strictures close to the hepatic hilum (Bismuth types II, III, and IV), a 7F plastic stent was inserted in the contralateral hepatic duct to maintain its patency. Stent extraction was planned after 6 to 12 months. Results: All stents were inserted successfully. After a median indwell time of 10 months (range, 3-15 months), all stents were successfully extracted. Strictures resolved in 10 patients (91%) at the time of stent extraction. One patient had premature extraction of the stent at 3 months due to stent obstruction. After a median follow-up of 24 months (range, 10-52 months), stricture recurrence occurred in 4 (40%) of 10 patients. No stent migration occurred, nor were there any cases of unilateral bile duct obstruction by the metallic duct. Conclusions: In postcholecystectomy biliary strictures, intraductal, fully covered metallic stents were effective even in strictures close to or involving the biliary bifurcation when an additional 7F plastic stent was inserted. Effective long-term stricture resolution was achieved in a substantial proportion of patients using a low number of endoscopic procedures and no reported stent migration.
