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

backgroundThere are very few randomised, blinded trials comparing laparoscopic sleeve gastrectomy (LSG) versus laparoscopic Roux-en-Y gastric bypass (LRYGB) in achieving remission of type 2 diabetes (T2D), particularly silastic ring (SR)-LRYGB. We compared the effectiveness of (LSG) versus SR-LRYGB among patients with T2D and morbid obesity.

methodsProspective, randomised, parallel, 2-arm, blinded clinical trial conducted in a single Auckland (New Zealand) centre. Eligible patients aged 20-55 years, T2D of at least 6 months duration and BMI 35-65 kg/m

resultsMean ± standard deviation (SD) pre-operative BMI was 42.5 ± 6.2 kg/m

conclusionDespite significantly greater weight loss after SR-LRYGB, there was similar T2D remission and psychosocial improvement after LSG and SR-LRYGB at 1 year.

trial registrationProspectively registered at Australia and New Zealand Clinical Trials Register (ACTRN 12611000751976) and retrospectively registered at Clinical Trials (NCT1486680).
