Weight Recurrence in Individuals Undergoing Bariatric Surgery According to Different Cutoff Points and its Association with Cardiometabolic Risk Variables.
Observational study in Obesity surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionBariatric surgery is effective in treating severe obesity, but weight recurrence (WR) after the procedure is a growing concern. The lack of consensus on cutoff points to define WR and its association with comorbidities is still a gap in the literature.
objectiveTo evaluate the prevalence of WR obtained through different cutoff points in patients who underwent bariatric surgery and its association with cardiometabolic risk markers.
methodsA cross-sectional observational study was carried out with patients who underwent bariatric surgery more than two years ago through the public health system from 2011 to 2019. Data collection was performed in person and remotely, with an assessment of anthropometric and metabolic variables. WR was analyzed in different percentages (15%, 25%, 35%, 45%) and associated with metabolic and biochemical variables.
resultsNinety-five individuals participated in this study; 84.2% were women aged 43 years (range 22 to 66 years). Individuals with WR ≥ 15% had significantly higher insulin and HOMA-IR values vs. WR < 15%, while those with WR ≥ 25% also had reduced ferritin levels and higher TyG index values vs. WR < 25%. For the first time, it was observed that subjects with WR ≥ 35% had higher triglyceride levels vs. WR < 35%. No significant difference in metabolic variables was observed when WR ≥ 35% was compared with WR ≥ 45%.
conclusionWR ≥ 15% was associated with some cardiometabolic risk markers, and these remain as WR increases.
