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.

Abstract

backgroundThe preferred surgical procedure for treating morbid obesity is debated. Patient-reported outcome measures (PROMs) are relevant for evaluation of the optimal bariatric procedure.

methodsA total of 113 patients with BMI from 50 to 60 were randomly assigned to standard (n = 57) or distal (n = 56) Roux-en-Y gastric bypass (RYGB). Validated PROMS questionnaires were completed at baseline and 2 years after surgery. Data were analyzed using mixed models for repeated measures and the results are expressed as estimated means and mean changes.

resultsObesity-related quality of life improved significantly after both procedures, without significant between-group differences (- 0.4 (95% CI = - 8.4, 7.2) points, p = 0.88, ES = 0.06). Both groups had significant reductions in the number of weight-related symptoms and symptom distress score, with a mean group difference (95% CI) of 1.4 (- 0.3, 3.3) symptoms and 5.0 (2.9. 12.8) symptom distress score points. There were no between-group differences for uncontrolled eating (22.0 (17.2-26.7) vs. 28.9 (23.3-34.5) points), cognitive restraint (57.4 (52.0-62.7) vs. 62.1 (57.9-66.2) points), and emotional eating (26.8 (20.5-33.1) vs. 32.6 (25.5-39.7) points). The prevalence of anxiety was 33% after standard and 25% after distal RYGB (p = 0.53), and for depression 12 and 9%, respectively (p = 0.76).

conclusionsThere were no statistically significant differences between standard and distal RYGB 2 years post surgery regarding weight loss, obesity-related quality of life, weight-related symptoms, anxiety, depression, or eating behavior.
