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

objectiveTo study if metformin, when administered to first-degree relatives of type 2 diabetes mellitus subjects who have metabolic syndrome and normal glucose tolerance, could improve the cardiovascular risk profile and reduce the levels of both C-reactive protein and fibrinogen.

introductionMetabolic syndrome is associated with higher cardiovascular morbidity and mortality. Metformin has vasculo-protective effects even in normoglycemic subjects, and C-reactive protein and fibrinogen are considered markers of endothelial injury and inflammation.

methodsThirty-one non-diabetic first-degree relatives of type 2 diabetes mellitus subjects with metabolic syndrome were randomized (1:1) and double-blinded for placement in the placebo and metformin groups (850 mg bid/+/-90 days); 16 subjects were administered metformin (mean age 40.0 [33.5-50] years; 13 females) and 15 subjects were in the placebo group (mean age 37.0 [32-42] years; 9 females). Blood samples were collected at baseline and at the end of treatment for biochemical analyses, including an assessment of C-reactive protein and fibrinogen levels.

resultsMetformin improved the lipid profile and decreased fasting plasma glucose, systolic blood pressure, weight and body mass index without changing body composition. For those in the placebo we identified no changes in fibrinogen (282.2 [220.4-323.7] mg/L vs. 286.7 [249.6-295.1] mg/L; NS) or in C-reactive protein levels (0.68 [0.3-1.2] vs. 0.64 [0.3-1.0] mg/L; NS). The same was also observed for the levels of fibrinogen (303.9 [217.6-347.6] mg/L vs. 290.9 [251.5-301.9] mg/L; NS) and C-reactive proteins (0.78 [0.3-1.1] vs. 0.80 [0.4-0.9] mg/L; NS) in the metformin group.

conclusionsMetformin treatment in first-degree relatives of type 2 diabetes mellitus sufferers who have metabolic syndrome and normal glucose tolerance improved the cardiovascular risk profile without changing the levels of C-reactive protein and fibrinogen.
