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

backgroundObesity and obesity-related comorbidities are associated with increased risk of coronary artery disease (CAD). Bariatric surgery results in durable weight loss and improvement in numerous CAD risk factors, yet limited data exist on CAD-related outcomes. We hypothesized that bariatric surgery would lead to decreased risk of CAD and reduced rates of coronary revascularization procedures.

methodsAll patients who underwent bariatric surgery at a single medical center from 1985 to 2015 were identified. A control population of morbidly obese patients who did not undergo bariatric surgery was identified using an institutional clinical data repository over the same study period, propensity score matched 1:1 on patient demographics and comorbidities including cardiac history. Univariate analyses were performed to compare outcomes in the surgery and non-surgery groups.

resultsA total of 3410 bariatric surgery patients and 45,750 non-surgical patients were identified. After 1:1 propensity-score matching, a total of 3242 patients in each group were found to be well balanced in baseline characteristics and risk factors. With a median follow-up of greater than 6 years, the surgery group had significantly lower rates of myocardial infarction (1.8% vs. 10.0%; RR 0.18), coronary catheterization (1.9% vs. 8.8%; RR 0.22), percutaneous coronary intervention (0.4% vs. 7.8%; RR 0.05), and coronary artery bypass grafting (0.6% vs. 2.3%; RR 0.26). Similar benefits were observed for subgroups of patients with and without diabetes.

conclusionsBariatric surgery was associated with a significant reduction in the incidence of myocardial infarction as well as lower rates of coronary revascularization in a propensity-matched cohort of morbidly obese patients. Though the retrospective nature of this study may have introduced a degree of selection bias, these outcomes support increased utilization of bariatric surgery for the prevention of heart disease.
