Covered Self-Expanding Metal Stents Versus Multiple Plastic Stents in Treating Biliary Strictures Post-Orthotopic Liver Transplantation: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.
Review in DEN open, 2026. 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
Objectives: Anastomotic biliary strictures are a common complication following orthotopic liver transplantation (post-OLT), impacting morbidity and graft survival. This meta-analysis evaluates the efficacy, safety, and cost-effectiveness of covered self-expanding metal stents (cSEMS) versus multiple plastic stents (MPS) for treating post-OLT strictures. Methods: A systematic review was conducted in PubMed, Cochrane Central, Embase, Scholar, and SciELO. We analyzed randomized controlled trials (RCTs) comparing cSEMS and MPS in post-OLT biliary strictures. Outcomes included stricture resolution, recurrence, endoscopic retrograde cholangiopancreatography sessions, adverse events, and cost. Standardized mean differences (SMDs) and risk ratios (RRs) were calculated with 95% confidence intervals (CIs). Cost-effectiveness analysis covered direct and indirect expenses. Results: Five RCTs with 269 patients were analyzed. No significant differences were found between cSEMS and MPS in terms of stricture resolution (RR = 1.01; 95% CI [0.90, 1.13]; Conclusion: cSEMS and MPS demonstrate similar efficacy and safety for post-OLT biliary strictures. Both strategies are viable, with selection based on cost, anatomy, and institutional resources.
