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

backgroundFew studies have looked at non-surgical alternatives for morbid obese patients. This study aims to compare 1-year weight loss and changes in risk factors and comorbidities after bariatric surgery and three conservative treatments.

methodsPatients with morbid obesity (BMI > 40 or BMI > 35 kg/m(2) plus comorbidities) on waiting list for bariatric surgery, were non-randomly allocated to (A) bariatric surgery or to one of three conservative treatments; (B) residential intermittent program; (C) commercial weight loss camp and (D) hospital outpatient program. Body weight, risk factors and comorbidities were assessed at baseline and 1 year.

resultsOf 206 participants, 179 completed the study. All treatments resulted in significant weight loss, but bariatric surgery (40 ± 14 kg, 31 ± 9%) led to the largest weight loss (P < 0.0001). There were no differences in weight loss between B and C (22 ± 13 kg, 15 ± 8% vs. 18 ± 12 kg, 13 ± 8%), but these resulted in larger weight loss compared with D (7 ± 10 kg, 5 ± 8%). There were no differences in changes in total or LDL cholesterol, triacylglycerols or glucose between groups; however, the increase in HDL cholesterol was significantly larger in groups A and C. There were no differences in comorbidities resolution between groups A and B, C and D combined (except hypertension, which was better in group A).

conclusionIn conclusion, although bariatric surgery leads to a greater weight loss at 1 year compared with conservative treatment, in patients with morbid obesity, clinical significant weight loss and similar improvements in risk factors and comorbidities resolution can also be achieved with lifestyle interventions.
