Long-Term (> 6 Years) Outcomes of Duodenal Switch (DS) Versus Single-Anastomosis Duodeno-Ileostomy with Sleeve Gastrectomy (SADI-S): a Matched Cohort Study.
Article in Obesity surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 papers, 4 of them syntheses that pooled it.
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
backgroundThere are no comparative studies on the long-term outcomes after the primary traditional duodenal switch (DS) and single-anastomosis duodeno-ileostomy with sleeve gastrectomy (SADI-S). PURPOSE: This study aims to compare the long-term outcomes in a matched cohort.
settingThis study took place in a single private institute, in the USA. MATERIALS AND
methodsData from 266 patients who underwent a primary laparoscopic traditional DS or primary laparoscopic SADI-S from September 2011 to December 2015 by four surgeons were used for a retrospective matched cohort. Data were obtained by matching every DS patient to a SADI-S patient of the same age, sex, and body mass index (BMI). In addition, only patients that were out at least 5 years and had a minimum 5-year follow-up were included in the study.
resultsThe matched cohort included 30 DS and 30 SADI-S patients. There were no statistically significant differences in the preoperative characteristics and baseline comorbidities between both groups. The SADI-S patients had significantly shorter operative time and length of stay. The overall long-term complications, especially the long-term Clavien-Dindo grade IIIb complications, were significantly fewer with SADI-S. At 6 years, the DS patients had statistically higher %EWL; however, the ending BMIs were statistically similar between both groups. There were no significant differences in the long-term comorbidity and nutritional outcomes of both groups. The long-term failure rates were comparable.
conclusionsMost long-term outcomes of SADI-S were either similar or significantly better than DS. Part of the reasons could be the surgeon's learning curve and the small sample sizes of both groups.
