Revisional Laparoscopic SADI-S vs. Duodenal Switch Following Failed Primary Sleeve Gastrectomy: a Single-Center Comparison of 101 Consecutive Cases.
Article in Obesity surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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.

Abstract
backgroundSingle-anastomosis duodeno-ileal bypass (SADI-S) is being proposed for obese patients with insufficient weight loss or weight regain after sleeve gastrectomy (SG), but limited information is available. The purpose of this study is to assess the safety and efficacy of SADI-S as a revisional surgery after SG, compared with standard duodenal switch (DS).
methodsUnicentric cohort study including all patients submitted to SADI-S and DS after failed SG in a high-volume institution, between 2008 and 2020.
resultsForty-six patients submitted to SADI-S and 55 to DS were included, 37.2 and 41.5 months after SG (p = 0.447), with initial BMI of 56.2 vs. 56.6 (p = 0.777) and 39.2 vs. 39.7 before revisional surgery (p = 0.675). All surgeries were laparoscopic. Clavien-Dindo > II complication rate was 6.5% for SADI-S and 10.9% for DS (p = 0.095), with no 90-day mortality. Follow-up at 2 years was available for 38 SADI-S' and 38 DS' patients, with total weight loss of 35.3% vs. 41.7% (p = 0.009), and excess weight loss 64.1% vs. 75.3% (p = 0.014). Comorbidities resolution for SADI-S and DS was: 44.4% vs. 76.9% for diabetes (p = 0.029) and 36.4% vs. 87.5% for hypertension (p = 0.006); with no differences for resolution of dyslipidemia (72.7% vs. 88.9%, p = 0.369) and obstructive sleep apnea (93.3% vs. 91.7%, p = 0.869). DS' patients required more extra nutritional supplementation. Three SADI-S patients needed conversion to DS, two for biliary reflux and one for weight regain.
conclusionAfter a failed SG, revisional DS permits better weight control and diabetes and hypertension resolution than SADI-S, at the expense of higher supplementation needs.
