Routine Upper Gastrointestinal Series Post-bariatric Surgery: Predictors, Usage, and Utility.
Article in Obesity surgery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveTo investigate usage and utility of routine upper gastrointestinal (UGI) series in the immediate post-operative period to evaluate for leak and other complications.
methodsSingle institution IRB-approved retrospective review of patients who underwent bariatric procedure between 01/08 and 12/12 with at least 6-month follow-up.
resultsOut of 135 patients (23%) who underwent routine UGI imaging, 32% of patients were post-gastric bypass (127) versus 4% of sleeve gastrectomy (8). In patients post-gastric bypass, 22 were found with delayed contrast passage, 3 possible obstruction, 4 possible leak, and only 1 definite leak. In patients post-sleeve gastrectomy, 2 had delayed passage of contrast without evidence of a leak. No leak was identified in 443 patients (77%) who did not undergo imaging. The sensitivity and specificity of UGI series for the detection of leak in gastric bypass patients were 100% and 97%, respectively, and the positive and negative predictive values were 20% and 100%, respectively. On univariate and multivariate analysis, sleeve gastrectomy patients (OR 0.4 sleeve vs bypass; P < 0.01) and male patients (OR 0.4 M vs F; P 0.02) were less likely to undergo routine UGI series (OR 0.4 M vs F; P 0.02).
conclusionRoutine UGI series may be of limited value for the detection of anastomotic leaks after gastric bypass or sleeve gastrectomy and patients should undergo routine imaging based on clinical parameters. Gastric bypass procedure and female gender were factors increasing the likelihood of routine post-operative UGI. Further larger scale analysis of this important topic is warranted.
