Biliary drainage in inoperable malignant biliary distal obstruction: A systematic review and meta-analysis.
Article in World journal of gastrointestinal surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers, 1 of them a synthesis that pooled 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.
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
backgroundEndoscopic drainage remains the treatment of choice for unresectable or inoperable malignant distal biliary obstruction (MDBO).
aimTo compare the safety and efficacy of plastic stent (PS)
methodsThis meta-analysis was developed according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. A comprehensive search was performed in MEDLINE, Cochrane, Embase, Latin American and Caribbean Health Sciences Literature, and grey literature to identify randomized clinical trials (RCTs) comparing clinical success, adverse events, stent dysfunction rate, reintervention rate, duration of stent patency, and mean survival. Risk difference (RD) and mean difference (MD) were calculated and heterogeneity was assessed with
resultsTwelve RCTs were included in this study, totaling 1005 patients. There was no difference in clinical success (RD = -0.03, 95% confidence interval [CI]: -0.01, 0.07;
conclusionWhile both stent types possessed a similar clinical success rate, complication rate, and patient-associated mean survival for treatment of MDBO, SEMS were associated with a longer duration of stent patency compared to PS.
