Demographic Factors Associated with Postoperative Complications in Primary Bariatric Surgery: A Rapid Review.
Synthesis in Obesity surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundBariatric surgery is highly effective for the management of severe obesity, but its safety profile is not completely understood. This review aimed to synthesise evidence linking demographic factors to postoperative complications and mortality following primary bariatric surgery.
methodsWe searched Medline for observational studies of adult patients linking demographic factors to postoperative complications of primary bariatric surgery published from 2017 to 2022. Risk ratios (RR) with 95% confidence intervals (95% CI) were calculated and pooled using random effect meta-analysis. Heterogeneity was quantified using the I
resultsA total of 71 observational studies (69 cohort, 2 case-control) were reviewed and appraised. Older age was consistently associated with increased risks of postoperative mortality (RR = 2.62, 95% CI 1.63-4.23, I
conclusionsOlder age and certain demographic factors (male sex, Black/African American race, low financial status, marital status) were associated with increased risks of postoperative complications following primary bariatric surgery.
