Effect of covered self-expanding metal stents compared with multiple plastic stents on benign biliary stricture: A meta-analysis.
Synthesis in Medicine, 2018. 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 placement of multiple plastic stents (MPS) has been the first-line treatment for benign biliary stricture (BBS). Covered self-expanding metal stents (cSEMS) have been used in treatment of BBS; however, the efficacy has not been verified. Therefore, we conducted this meta-analysis according to PRISMA guidelines.
methodsPubMed, Embase, and the Cochrane Library were electronically and manually searched for studies published between January 1, 1990 and April 12, 2017. Of 153 studies screened, 90 were excluded because of duplications. After scanning the title or abstract, only 24 studies were eligible for review and 6 were finally included. The investigators selected publications according to inclusion and exclusion criteria, processed the data, and assessed the quality of the selected studies. The primary endpoint outcome was stricture resolution, and the secondary endpoint outcomes included stricture recurrence rate, the number of endoscopic retrograde cholangiopancreatography (ERCP) sessions, and stent migration.
resultsA total of 6 randomized controlled trials with 330 participants were included in the current meta-analysis. There was no significant difference in stricture resolution between the cSEMS and MPS groups (odds ratio [OR] = 1.05, 95% confidence interval [CI] = 0.53-2.07, I = 29%, P = .23, Z = 0.13, P = .90). Similarly, the stricture recurrence rates (OR = 1.39, 95% CI = 0.69-2.81, I = 38%, P = .17, Z = 0.91, P = .36) were comparable between cSEMS and MPS groups. Stent migration rates (OR = 1.71, 95% CI = 0.84-3.50, I = 4%, P = .241, Z = 1.47, P = .14) were similar between cSEMS and MPS groups. There were fewer ERCP sessions in the cSEMS group than in the MPS group.
conclusionsThis meta-analysis showed that cSEMS were comparable to MPS in achieving resolution of BBSs with fewer ERCP procedures.
