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
backgroundPer oral endoscopic myotomy (POEM) is used to treat a variety of esophageal motility disorders and is associated with relatively few complications. However, complications in patients on antithrombotic therapy (AT) is not well-studied. We hypothesize AT patients have a higher risk of post-operative bleeding and 30-day complication rate compared to all other patients, even when these medications are held peri-operatively.
methodsA single-institution retrospective review of a prospectively collected database of patients who underwent POEM procedures January 2011-July 2019 was performed. All 30-day complications were recorded, as well as management of AT medications peri-operatively. Demographic and clinical characteristics were compared using t test, Chi-Square, and Fisher's exact test as appropriate. Multivariate logistic regression was performed to examine factors associated with post-operative complications.
resultsA total of 219 POEM procedures were performed. 50.2% of patients were male, and AT patients tended to be older (66.9 vs. 55.4, p = 0.01). The major complication rate was higher among AT patients (36.8% vs. 9.0%, p = 0.01), as was the rate of post-operative bleeding (10.5% vs. 1.0%, p = 0.04). After adjusting for gender and age, the use of antithrombotic therapy was significantly associated with 30-day complications (OR 6.03, p = 0.001).
conclusionsPatients on AT who undergo POEM are significantly more likely to experience complications, including bleeding, within 30 days of surgery. Safe timing of post-operative resumption of antithrombotic medications remains a difficult decision that must be carefully considered by the endoscopist.
