1 · What the graph read from 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.

2 · The registry

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

purposeThere are only a small number of studies providing a comparison between SADI-S and Hess-Marceau's BPD/Duodenal Switch (RY-DS) operations. We aimed to compare 5-year results of SADI-S 250 (common limb 250 cm) with RY-DS. MATERIAL AND

methodsData of patients who underwent open SADI-S (n 226) and RY-DS (n 528) were retrospectively studied. EWL(%), EBMIL(%), TWL(%), antidiabetic effect, complications, and revision rate were compared between the two groups.

resultsAfter the first 12 months, EWL% (77.0% vs 73.3%) and TWL% (39.4% vs 38.9%) were statistically significantly better after SADI-S (p < 0.01, and p < 0.05 respectively), but not EBMIL% (p > 0.05). At nadir to 24-36 months, EWL, TBWL, and EBMIL after SADI-S was comparable to the RY-DS group. Up to the fourth and fifth year, better weight loss (TBWL, EBMIL, EWL) was observed after RY-DS than after SADI-S. Early complication rate was less (2.65%) in the SADI-S group vs 5.1% in the RY-DS. Protein deficiency and small bowel obstruction rates were also lower after SADI-S. 93.4% of patients achieved total remission of their diabetes. 7.5% of patients in the SADI-S group had symptoms of bile reflux, which was a main indication for revisions.

conclusionSADI-S has many advantages over RY-DS. However, weight loss and antidiabetic effects after the third year were marginally lower after SADI-S compared to RY-DS. SADI-S is less dangerous in terms of malabsorption and looks to be a reasonable alternative to RY-DS as a metabolic operation. RY-DS could be implemented for weight regain and/or bile reflux after SADI-S.
