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

A diet rich in fruits, vegetables and low-fat dairy products, and reduced in saturated fat, total fat and cholesterol (the 'DASH' diet) significantly lowers blood pressure (BP). Previous studies have documented that certain therapies that lower BP increase plasma renin activity (PRA). Using data from the Dietary Approaches to Stop Hypertension (DASH) trial, we assessed the effects of dietary patterns on PRA and determined the relationship of change in PRA with change in BP on each diet. After eating a control diet for 3 weeks, participants were then randomized to receive for 8 weeks: the control diet, a diet rich in fruits and vegetables (F/V), or the DASH diet. Baseline and follow-up levels of PRA were available in 381 participants. Compared with the control diet, the DASH diet increased PRA by 0.37 ng ml(-1) h(-1) (P=0.01). In multivariable linear regression analyses, there was an inverse association of PRA change with systolic BP change on the control diet (slope=-0.35, P=0.001), but PRA did not differ by BP change on the F/V diet (slope=-0.002, P=0.98) or DASH diet (slope=-0.08, P=0.32). These data suggest that a blunted counter-regulatory response of the renin-angiotensin system is associated with the BP-lowering effect of the F/V and DASH diets.
