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

BACKGROUND/

objectivesThere is limited long-term data comparing the outcomes of sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) for severe obesity, both with respect to body weight, quality of life (QOL) and comorbidities. We aimed to determine 7-year trajectories of body mass index (BMI), QOL, obesity-related comorbidities, biomarkers of glucose and lipid metabolism, and early major complications after SG and RYGB. SUBJECTS/

methodsPatients scheduled for bariatric surgery at two Norwegian hospitals, preferentially performing either SG or RYGB, were included consecutively from September 2011 to February 2015. Data was collected prospectively before and up to 7 years after surgery. Obesity-specific, generic and overall QOL were measured by the Impact of Weight on Quality of Life-Lite, Short-Form 36 and Cantril's ladder, respectively. Comorbidities were assessed by clinical examination, registration of medication and analysis of glucose and lipid biomarkers. Outcomes were examined with linear mixed effect models and relative risk estimates.

resultsOf 580 included patients, 543 (75% women, mean age 42.3 years, mean baseline BMI 43.0 kg/m

conclusionIn routine health care, both SG and RYGB are safe procedures with significant long-term weight-loss, improvement of QOL and amelioration of comorbidities. Long-term weight-loss and remission rates of main obesity-related comorbidities were higher after RYGB.
