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

backgroundSeveral observational studies have recently suggested an inverse association of circulating levels of vitamin D with blood pressure. These findings have been based mainly on Caucasian populations; whether this association also exists among Hispanic and African Americans has yet to be definitively determined. This study investigates the association of 25-hydroxyvitamin D (25[OH]D) with blood pressure in Hispanic and African Americans.

methodsThe data source for this study is the Insulin Resistance Atherosclerosis Family Study (IRASFS), which consists of Hispanic- and African-American families from three US recruitment centers (n =1,334). A variance components model was used to analyze the association of plasma 25[OH]D levels with blood pressure.

resultsAn inverse association was found between 25[OH]D and both systolic (beta for 10 ng/ml difference = -2.05; P < 0.01) and diastolic (beta for 10 ng/ml difference = -1.35; P < 0.001) blood pressure in all populations combined, after adjusting for age, sex, ethnicity, and season of blood draw. Further adjustment for body mass index (BMI) weakened this association (beta for 10 ng/ml difference = -0.94; P = 0.14 and beta for 10 ng/ml difference = -0.64; P = 0.09, respectively).

conclusions25[OH]D levels are significantly inversely associated with blood pressure in Hispanic and African Americans from the IRASFS. However, this association was not significant after adjustment for BMI. Further research is needed to determine the role of BMI in this association. Large, well-designed prospective studies of the effect of vitamin D supplementation on blood pressure may be warranted.
