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
backgroundBilateral endoscopic biliary stenting remains technically challenging, which limits its wider clinical application.
aimsWe have developed a novel long (10-12 cm) and slimmer (6 mm) self-expanded metal stent. The aim of this study was to evaluate the feasibility, efficacy, and safety of the new metal stent for palliative treatment of malignant hilar biliary strictures (MHBS).
methodsThis retrospective study of prospectively collected data included 45 patients with unresectable malignant hilar biliary strictures of Bismuth type II or higher. A pair of long slimmer metal stents were sequentially placed into the intrahepatic duct using the stent-by-stent mode. The success rate and short- and long-term clinical outcomes were observed.
resultsThe technical success rate was 100%, with a mean procedure time of 43.7 ± 11.5 min. The clinical success was achieved in 44 patients (97.8%). Early adverse events included mild acute pancreatitis (n = 2) and cholangitis (n = 3). Later cholangitis occurred in 14 of the 45 patients due to stent occlusions. The median stent patency was 260 days (95% CI 228.3-291.7). Stent malfunctions occurred in 23 of the 45 patients, and 15 of them received bilateral endoscopic plastic stents placements. The technical success for the re-intervention was 100% with the mean procedure time of 24.3 ± 4.5 min. The median overall survival of the whole group was 229 days (95% CI 171.2-286.8).
conclusionsThe long slimmer metal stent for bilateral endoscopic stent-by-stent placement proved to be safe, feasible, and effective for MHBS and facilitates endoscopic re-intervention as well.
