Risk factors for preterm birth in pregnancies following bariatric surgery: an analysis of the Longitudinal Assessment of Bariatric Surgery-2.
Article in Surgery for obesity and related diseases : official journal of the American Society for Bariatric Surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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 has been shown to increase the risk for preterm birth in a subsequent pregnancy. Determining factors that contribute to this heightened risk will inform the development of targeted interventions to improve birth outcomes postbariatric surgery.
objectivesThis study aimed to identify risk factors of preterm birth in pregnancies following bariatric surgery. Factors being considered were preoperative medical conditions and behaviors (e.g., obesity-associated co-morbidities, gastrointestinal symptoms, substance use), antenatal factors (e.g., prepregnancy body mass index, gestational weight gain), and surgery-specific factors (e.g., surgery type, surgery-to-conception interval).
settingBariatric surgery centers in the United States.
methodsThis is a retrospective analysis of the Longitudinal Assessment of Bariatric Surgery-2. Participants were women who reported at least 1 singleton live birth during the 7-year postoperative period. Logistic regressions were used to identify risk factors of preterm birth, adjusting for covariates such as maternal age, race, and ethnicity.
resultsParticipants (n = 97) were mostly White (84.5%) and non-Hispanic (88.7%). At the time of surgery, the mean age was 29.4 ± 4.6 years, and the mean body mass index was 47.6 ± 6.3 kg/m
conclusionsThis analysis identified potential risk and protective factors of preterm birth among pregnancies postbariatric surgery. However, given the small sample size, findings should be regarded as hypothesis-generating and merit further study.
