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.

Abstract
Background: : Peroral endoscopic myotomy (POEM) is an established modality of treatment for achalasia cardia. Considerable variations exist in the technique of POEM with respect to the length and orientation of the myotomy. In this systematic review and meta-analysis, we compared the outcomes of short versus long myotomy during POEM. Methods: : We searched multiple databases from January 2010 to March 2021 to identify studies reporting on POEM. We selected studies that reported on comparative outcomes of POEM using short versus long myotomy. We performed a comparative analysis of clinical success, procedural duration, gastroesophageal reflux disease (GERD), and adverse events with short and long myotomy in POEM by meta-analysis. Results: : A total of 521 patients from five studies in which 241 patients were treated with short and 280 patients with long myotomy approaches were analyzed. The pooled rate for clinical success gave an odds ratio (OR) of 1.27 (95% confidence interval [CI] 0.50-3.26; I Conclusion: : Short myotomy and long myotomy in POEM seem comparable with each other in terms of clinical success and adverse events. Short myotomy is associated with significantly shorter procedural duration and possibly reduced esophageal acid exposure compared with long myotomy.
