8-Year Outcomes After Sleeve Gastrectomy: Anthropometric, Biochemical, and Nutritional Evaluation.
Observational study in Obesity surgery, 2026. 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
introductionComprehensive long-term studies simultaneously evaluating anthropometric, biochemical, and nutritional outcomes after sleeve gastrectomy (SG) remain limited. This study aimed to compare preoperative findings with outcomes at postoperative year 8 and to explore factors associated with recurrent weight gain (RWG).
methodsThis longitudinal observational study involved the prospective reassessment of a retrospectively defined cohort of patients who underwent SG between 2016 and 2017. Anthropometric measurements, biochemical parameters, dietary intake, lifestyle behaviors, and associated medical conditions were evaluated both preoperatively and at the 8-year postoperative follow-up. RWG and suboptimal clinical response were defined according to IFSO consensus criteria. Nutritional intake was assessed using 3-day dietary records, and statistical analyses were conducted using non-parametric methods.
resultsReductions were observed in body weight, waist circumference, waist-to-hip ratio, and body fat percentage (p < 0.05). Improvements in cardiometabolic parameters were also observed, including lower fasting glucose and HOMA-IR levels and more favorable lipid profiles. RWG was identified in 52.2% ofpatients when assessed using current weight. Higher energy intake and less favorable dietary patterns, including increased refined carbohydrate intake, were observed among patients with RWG. Differences in meal timing and adherence to postoperative eating recommendations were also observed between groups. Despite attenuation of peak weight loss over time, metabolic benefits were largely maintained.
conclusionLong-term outcomes after SG involve both initial weight loss and sustained behavioral adaptation. RWG was observed in a substantial proportion of patients; however, overall weight loss and metabolic improvements were largely preserved. Given the exploratory nature and limited sample size, findings should be interpreted with caution, and further prospective studies are needed.
