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
backgroundCaustic-induced gastric outlet obstruction (GOO) remains one of the important causes of long-term morbidity in patients with caustic ingestion. Though endoscopic balloon dilation is an effective modality, response to caustic GOO is poorer as compared to peptic stricture. Computed tomography (CT)-antral wall thickness (AWT) has not been previously explored to predict the procedural success in patients with caustic GOO.
methodsIn a retrospective single-center study of prospectively maintained database, all patients with symptomatic caustic GOO who underwent CT scan prior to endoscopic balloon dilation were included. Gastric AWT was measured at the site of maximum visible thickness on CT scan. Details regarding caustic ingestion and endoscopic dilation were retrieved. Patients were divided into two groups, based on CT-AWT (< or ≥9 mm) and compared for outcome measures.
resultsMean age of included patients (n=35) was 33.51 ± 13.65 years and 22 were male. Procedural success was achieved in 29 (82.85%) patients. Number of mean dilation sessions required were 5.28 ± 2.96 for achieving procedural success. The mean CT-AWT was 10.73 ± 2.80 mm (range 4-18 mm). There was no significant association between the CT-AWT and the number of dilations and procedural success. On univariate analysis, size of the first balloon used was a predictor of refractory stricture (p=0.011). However, no other factors predicted either refractory stricture or procedural success.
conclusionThere is no additional role of CT-AWT in predicting response to endoscopic balloon dilation or to predict refractory stricture in patients with caustic GOO.
