Stent Management of Leaks After Bariatric Surgery: a Systematic Review and Meta-analysis.
Synthesis in Obesity surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
backgroundDespite the low rates of complications of bariatric surgery, gastrointestinal leaks are major adverse events that increase post-operative morbidity and mortality. Endoscopic treatment using self-expanding stents has been used in the therapeutic management of these complications with preliminary good results.
methodsWe performed a systematic review and meta-analysis of self-expanding stents placement for the management of gastrointestinal leaks after obesity surgery. Overall proportion of successful leak closure, stent migration, and reoperation were analysed as primary outcomes. Secondary outcomes were patients' clinical characteristics, duration and type of stent, other stent complications, and mortality.
resultsA meta-analysis of studies reporting stents was performed, including 488 patients. The overall proportion of successful leak closure was 85.89% (95% CI, 82.52-89.25%), median interval between stent placement and its removal of 44 days. Stent migration was noted in 18.65% (95% CI, 14.32-22.98%) and the overall proportion of re-operation was in 13.54% (95% CI, 9.94-17.14%). The agreement between reviewers for the collected data gave a Cohen's κ value of 1.0. No deaths were caused directly by complications with the stent placement.
conclusionsEndoscopic placement of self-expanding stents can be used, in selected patients, for the management of leaks after bariatric surgery with a high rate of effectiveness and low mortality rates. Nevertheless, reducing stent migration and re-operation rates represents an important challenge for future studies.
