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

objectivePart of the beneficial effects of metformin on the prevention of cardiovascular events in diabetes can be attributed to pleiotropic effects, including a blood pressure (BP)-lowering effect. In a double-blind parallel clinical trial (NCT02072382), the effect of metformin on BP evaluated by ambulatory blood pressure monitoring (ABPM) was measured.

methodsNinety-seven patients with hypertension, but without diabetes mellitus, were randomized to receive 850-1700 mg of metformin (n = 48) or placebo (n = 49). Clinical, laboratory, and ABPM data were collected at the baseline and after 8 weeks of follow-up.

resultsThe sample consisted mainly of White overweight women. There was no difference in BP reduction measured by ABPM between both groups. There was no effect in BP measured in the different periods of ABP monitoring and office BP. Additionally, fasting plasma glucose, lipids, and C-reactive protein remained unchanged during the trial. There was a significant reduction in waist circumference with metformin (95.1 ± 10.4 to 89.3 ± 27.4 cm; p = 0.02).

conclusionIn the present trial, metformin did not reduce BP, measured by ABP monitoring, in hypertensive patients without diabetes.
