1 · What the graph read from 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.

2 · The registry

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

purposeThis study aims to assess the safety and clinical outcomes of novel biodegradable biliary stents (BDBS) in the treatment of benign biliary strictures (BBS). MATERIALS AND

methodsA systematic literature search on BDBS placement for BBS was conducted in Medline. Studies reporting technical success, clinical success, and BBS recurrence rates were included. A meta-analysis of proportions was used to determine each of the outcomes.

resultsTwelve studies involving 384 patients who underwent 387 BDBS placement for BBS were included. The weighted pooled proportion of technical success was 100% (95% CI 92-100%). After a mean follow-up of 23.3 months, the weight average clinical success was 81% (95% CI 76-85%) and stricture recurrence was 20% (95% CI 14-27%). The mean time to relapse was 11.8 months. Stent migration, complication, and readmission rate were 3% (95% CI 2-6%), 11% (95% CI 5-22%), and 2% (95% CI 0-100%), respectively. No mortality was reported.

conclusionBDBS placement is safe and effective treatment for BBS, with high technical and clinical success with acceptable complication and migration rates. LEVEL OF EVIDENCE: Level 3.
