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

backgroundIn bariatric surgery, a significant question remains unanswered-What proportion of weight loss comes from each component and does this differ with time? Single anastomosis duodenal switch (LDS) combines a vertical sleeve gastrectomy (VSG) with a loop attachment of the duodenal stump. There are two major variables the sleeve, and the intestine that processes ingested food. A comparison of patients that had a VSG with those that have had a LDS approximates the contribution of each component.

methodsA retrospective matched cohort analysis of VSG and LDS patients was obtained by matching every LDS patient to a VSG patient of the same sex and BMI. Excess weight lost percentage (%EWL) and the total weight loss percentage (%TWL) was analyzed. The data was compared through descriptive statistics and non-linear regression analysis.

resultsOver 18 months, patients who received the LDS lost more %TWL and %EWL and the difference was statistically significant (p < 0.05). Additionally, with time, the difference became more profound. Weight loss stabilized at approximately 9-12 months and 15 to 18 for VSG and LDS patients', respectively. At 6 months post op, there was approximately 13 % difference in weight loss. This increased to 29 % difference at 18 months.

conclusionLDS patients lose more weight than VSG. Preserving 3 m of intestinal length adds 30 % greater weight loss at 18 months. Early weight loss is similar between the two operations, while the intestinal component becomes more important with weight loss differentials increasing as time since surgery lengthens.
