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
backgroundPeroral endoscopic myotomy (POEM) is an innovative achalasia treatment procedure that involves myotomy of the lower esophageal sphincter through a submucosal tunneling approach, combining the efficacy of surgical myotomy with the benefit of being a less invasive treatment. At this time, no data are available of POEM in Portugal. This study aimed to examine the safety and short-term outcomes of POEM in a Portuguese center.
methodsFifty POEM were performed on 49 consecutive patients at our institution between January 2017 and January 2020. A prospective study of a consecutive series of patients was conducted, including procedure time, myotomy location and length, adverse events and clinical success. An Eckardt score of ≤3 after POEM was deemed as a successful outcome. Gastroesophageal reflux disease (GERD) was evaluated based on symptoms and on upper endoscopy, which was performed at 3-6 months postoperatively to check for reflux esophagitis.
resultsPOEM was successfully completed in all cases: 70% (
conclusionsOur results confirm the safety and excellent short-term efficacy of POEM in a Portuguese center. This supports POEM as one of the first-line achalasia therapies in Portugal when performed by experienced operators.
