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

introductionSingle-anastomosis duodenoileal bypass (SADI) is an efficacious conversion operation to address suboptimal clinical response after sleeve gastrectomy (SG). Controversy remains regarding optimal length of the common channel for weight loss and potential adverse outcomes. The purpose of this study was to analyze conversion of SG to SADI, comparing 250 cm (SADI-250) to 300 cm (SADI-300) common channel length.

methodsData were collected from n = 63 patients (n = 40 SADI-250; n = 23 SADI-300) that underwent conversion of SG to SADI in a single metabolic and bariatric surgery center of excellence. The primary outcome was percent total weight loss (%TWL). Secondary outcomes were reoperations and nutrition-related complications.

resultsThree-year follow-up rates for SADI-250 patients were 90% (n = 36) and for SADI-300 were 91% (n = 21). Compared to SADI-300 patients, SADI-250 experienced greater %TWL throughout follow-up (p < .001). SADI-250 patients continued to lose weight through three years; while SADI-300 patients began to regain weight at 12 months. At the end of three years, SADI-250 patients lost 15.1% more weight than SADI-300 patients. There were three reoperations, one for the SADI-300 and two for the SADI-250 and no significant nutritional complications in either group.

conclusionThe SADI-250 operation was associated with significantly greater weight loss at three years compared to SADI-300, with no differences in complications between the two operations. Conversion of SG to SADI using a 250 cm common channel led to significant additional weight loss (25.7% TWL at three years).
