1 · What the graph read from it

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.

2 · The registry

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

backgroundLimited literature exists on labor and delivery outcomes after bariatric surgery. This study assesses the impact of prior bariatric surgery on peripartum outcomes.

methodsWe queried the National Inpatient Sample (2016-2020) for labor and delivery admissions, categorizing them into three cohorts: prior bariatric surgery (BaS), obesity without prior bariatric surgery, and controls without obesity. We used a multivariate regression model, adjusting for confounders, to compare peripartum outcomes.

resultsWe identified 22,685 BaS cases, 2.1 million pregnant controls with obesity, and 16.37 million pregnant controls without obesity. Compared to controls with obesity, the BaS cohort had lower rates of cesarean delivery [43% vs 46.8%, adjusted odds ratio (aOR) 0.72, p < 0.001], fetal distress [aOR 0.79, p < 0.001), post-partum hemorrhage (aOR 0.67, p < 0.001), fetal disproportion (aOR 0.36, p < 0.001), and premature rupture of membranes (aOR 0.88, p = 0.04). Compared to controls without obesity, the BaS group had higher rates of cesarean delivery (43% vs 29.57%, aOR 1.43, p < 0.001), breech presentation (aOR 1.4, p < 0.001), thromboembolic events (aOR 2.47, p = 0.01), and pregnancy termination (aOR 1.59, p = 0.048), but lower rates of assisted delivery (aOR 0.54, p < 0.001), fetal disproportion (aOR 0.56, p = 0.025), PROM (aOR 0.87, p = 0.024), and placenta previa (aOR 0.63, p = 0.019). The BaS group had longer hospitalizations (3.11 vs 2.56 days, p < 0.001) and higher hospitalization charges ($25,941 vs $20,760, p < 0.001) compared to controls without obesity.

conclusionPregnancy after bariatric surgery is associated with lower odds of cesarean delivery and postpartum complications, relative to the general population with obesity. This underscores the positive impact of bariatric surgery on peripartum outcomes.
