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

backgroundMetabolic bariatric surgery (MBS) is the most effective obesity treatment. The increasing number of MBS among young patients has led to more post-bariatric pregnancies. Our study investigates how breastfeeding duration impacts postpartum weight retention and health outcomes for mothers and babies after MBS.

methodsMOMBARIS (Maternal Outcomes of Bariatric Surgery and Pregnancy Study) is a multicentre study. The population is derived from MOMBARIS 2, which focused on obstetric outcomes. It included patients who became pregnant following MBS, analysing pre-operative metrics, type of surgery, pregnancy details, and breastfeeding duration. Data analysis was conducted using Julius.ai.

resultsWe analysed 156 patients post-MBS, with 148 pregnancies leading to childbirth. Among them, 131 had laparoscopic sleeve gastrectomy (LSG), 12 underwent Roux-en-Y gastric bypass (RYGB), and 5 had one anastomosis gastric bypass (OAGB). The mean age was 31.7 ± 5.45 years (range 19-48) with a pre-operative BMI of 43.9 kg/m

conclusionsBariatric outcomes (%EWL, %TWL) show no statistical difference based on breastfeeding patterns, nor does breastfeeding significantly affect weight loss maintenance post-surgery. Additionally, delaying pregnancy after surgery does not guarantee more significant weight loss.
