Weight loss outcomes after Nissen sleeve gastrectomy vs standard sleeve gastrectomy in female patients: a retrospective matched -cohort study.

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
Introduction: Nissen sleeve gastrectomy (NSG) is a procedure that combines SG with an antireflux component. However, its impact on weight loss outcomes remains controversial. Comparative data between SG and NSG are limited. Aim: The aim of this study was to compare weight loss after NSG and SG at a minimum of 12 months postsurgery. Materials and methods: This retrospective matched-cohort study included patients who underwent NSG at a high-volume bariatric center between 2023 and 2025. The NSG patients were matched at a 1:2 ratio with individuals undergoing standard SG, using propensity score matching based on age, preoperative body mass index, and date of surgery. Weight loss outcomes, including percentage of total weight loss (%TWL) and percentage of excess weight loss (%EWL), were assessed at a minimum follow-up of 12 months. Subgroup analyses were performed according to follow-up duration (<20 vs ≥20 mo). Results: A total of 25 patients undergoing NSG were matched with 50 SG patients. All study participants were women. At median (interquartile range) follow-up of 20.4 (16-23.1) months, SG was associated with significantly higher %TWL and %EWL, as compared with NSG (32.2% vs 29.3%; Conclusions: SG was associated with greater early weight loss than NSG. However, these differences diminished with longer follow-up.
