Reproductive Outcomes Differ Following Roux-en-Y Gastric Bypass and Adjustable Gastric Band Compared with Those of an Obese Non-Surgical Group.

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
backgroundLittle is known about how bariatric surgery type may impact reproductive health outcomes. Our objective was to determine differences in infertility and birth outcomes among women who underwent Roux-en-Y gastric bypass (RYGB), adjustable gastric band (AGB), and an obese non-surgical group.
methodsWomen aged 18-45 who were evaluated for bariatric surgery were invited to complete a survey. Pre- and post-surgery outcomes were compared among women who underwent RYGB vs. AGB and to those of obese women who decided against surgery. Outcomes included infertility, time to conception from first attempt, use of infertility services, pregnancy, live birth, and birth weights. Logistic and linear regression, controlling for age, BMI, weight, and pregnancy history, were used to calculate odds ratios (ORs) and beta-coefficients with 95 % confidence intervals (CIs).
resultsTwo-hundred nineteen surveys were completed. RYGB resulted in a reduction in menstrual cycle irregularity after surgery compared to before (OR = 0.21, CI = 0.07-0.61). For first-pregnancy outcomes, there were lower odds of term birth after RYGB than before (OR = 0.21, CI = 0.05-0.90) and increased odds of miscarriage after RYGB compared to the no-surgery group (OR = 9.81, CI = 1.12-85.71). We found lower odds of live birth after AGB than before (OR = 0.19, CI = 0.05-0.73). Birth weight was significantly lower after RYGB but not AGB (p < 0.01).
conclusionsThis small study suggests that the impact of bariatric surgery may vary by procedure type and impact menstrual regularity, live birth, and offspring birth weight. These results should be considered pilot data and support performance of a prospective study to fully investigate these preliminary findings.
