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

backgroundWhile women may seek metabolic and bariatric surgery (MBS) to achieve pregnancy, conflicting data exist on how MBS affects pregnancy and fetal outcomes. Additionally, despite existing consensus recommendations for micronutrient monitoring, adherence to recommended screening is unknown.

objectivesEvaluate post-MBS pregnancy outcomes and clinical adherence to micronutrient monitoring recommendations.

settingUniversity Hospital, United States.

methodsA retrospective cohort study of singleton, live-birth pregnancies in post-MBS patients from 2008 to 2023 was performed. Mother and neonate weight, pregnancy comorbidities, peripartum outcomes, and micronutrient results were analyzed using descriptive statistics and Chi-square tests.

resultsIn 139 patients (99 Roux-en-Y gastric bypass (RYGB)/duodenal switch (DS) and 40 sleeve gastrectomy (SG)/adjustable gastric band (AGB)), we evaluated 169 singleton, live birth pregnancies. Mean body mass index (BMI) at MBS and preconception were 46.5 ± 8.7 and 34.0 ± 7.7 kg/m

conclusionsWe found that longer TTC and persistent obesity increased patient risk for peripartum complications. Support to help patients achieve lower preconception weight may reduce peripartum complications.
