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 super-obese patients, rates of weight loss failure and weight regain are high after RYGB. In order to improve weight loss, lengthening of the biliopancreatic limb is vital. In this study, efficacy and safety of two types of RYGB with 2-m BP-limb were assessed in improving weight loss and in the resolution of comorbidities compared with standard RYGB in a long-term follow-up.

methodsThis is a retrospective cohort analysis on 671 super-obese patients operated in a 10-year period. Patients were classified into three groups: (1) 155 patients; roux limb 150 cm, BP-limb 60 cm; (2) 230 patients; roux limb 60 cm, BP-limb 200 cm; and (3) 286 patients; roux limb 150 cm, BP-limb 200 cm. EWL, TWL, BMI, failure, weight regain, comorbidity resolution, nutritional status, and complications were assessed.

resultsTotal alimentary limb length was shortened with 60 cm in group 1 and with 200 cm in groups 2 and 3. EWL, BMI change, and TWL were higher in the 2-m BP-limb groups vs group 1. No differences in complication rates were found, except higher frequency of marginal ulcers in patients with a shorter roux limb. EWL failure was higher in group 1 (10.3%) vs the other groups (4.3%; 5.2%). Group 3 had significantly less weight regain (26.6%). Remission of comorbidities was higher in the 2-m BP-limb groups at expense of nutritional and vitamin deficiencies (3.9%; 5.9%). No difference in hypoalbuminemia was noted.

conclusionLengthening of the BP-limb gives significantly higher weight loss, lower rate of EWL failure, and lesser weight regain along with better resolution of obesity-associated comorbidities.
