Does Ethnicity Influence the Long-Term Outcomes of Sleeve Gastrectomy? Results from a Prospectively Maintained Israeli Database.
Article 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
backgroundEthnic disparities often influence patient's outcomes. This study aimed to compare the weight loss and metabolic outcomes of laparoscopic sleeve gastrectomy (LSG) in Israeli-Arab and Israeli-Jewish patients.
methodsA prospectively maintained cohort of 892 patients (262 Arabs and 630 Jews) who underwent LSG between 2009 and 2022 at a single tertiary academic center was retrospectively analyzed. Demographic, peri-operative, and long-term outcome data were compared between the two groups.
resultsArabs were younger (35 vs. 44 years) and had a higher baseline BMI (45.1 vs. 42.9). Jews had more postoperative follow-ups (6.8 vs. 6.0). Despite these differences, long-term weight loss outcomes were broadly comparable between groups. %EWL outcomes did not differ significantly at 1- and 5-year follow-up. Although Arab patients demonstrated numerically higher %TWL at 1 year, this difference did not reach statistical significance and was not sustained at longer-term follow-up. Rates of comorbidity remission, including diabetes, hypertension, and dyslipidemia, were similarly high.
conclusionDespite baseline ethnic disparities, LSG was associated with comparable long-term weight loss and comorbidity resolution among Israeli-Arab and Israeli-Jewish patients.
