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

backgroundPostoperative outcomes after metabolic and bariatric (MBS) can vary due to preoperative behaviors and psychological factors, with several eating patterns (EPs), including eating disorders (EDs), often associated with suboptimal weight loss. Some guidelines even consider EDs a contraindication for MBS. This study examined the impact of EPs on long-term outcomes after MBS.

methodsA retrospective analysis was conducted on prospectively collected data from 1550 patients who underwent primary Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) between 2010 and 2018. Patients were categorized based on preoperative EPs, including binge eating disorder (BED), snacking behavior (SB), sweet eating habit (SEH), fat eating habit (FEH), night eating syndrome (NES), excessive eating habit (EEH), or no present EP. Demographics, morbidity, weight loss, comorbidities, and complications were assessed over 5 years. Outcomes were measured using the SF-BARI score.

resultsEPs were common (67.6%), with many patients exhibiting multiple patterns. Patients with EPs were younger (40.8 vs. 43.3 years; p < 0.01) and had higher baseline BMI (44.5 vs. 43.8 kg/m

conclusionPreoperative EPs, including EDs, do not significantly impact postoperative outcomes after MBS, suggesting a need to reassess guidelines on EDs as contraindications.
