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

Resistant hypertension (RHTN) includes both patients whose blood pressure (BP) is uncontrolled on three or more medications (uncontrolled RHTN (UCRH)) and patients whose BP is controlled with use of four or more drugs (controlled RHTN (CRH)). It is unknown whether endothelial function and nocturnal drop demonstrate a similar pattern in patients with CRH and UCRH. We examined circadian BP patterns and vascular function in these patients. In all, 40 CRH and 26 UCRH patients, and 25 normotensives underwent biochemical testing, ambulatory BP monitoring, determination of brachial artery responses to endothelial-dependent (flow-mediated; dilation (FMD)) and independent (nitroglycerin mediated) stimuli. The nighttime drop in systolic BP (SBP) and diastolic BP (DBP) was less pronounced in UCRH than in CRH (SBP, 1.9±1.6 versus 4.9±1.7%; DBP, 7.5±1.8 versus 10.9±1.8%, UCRH and CRH, respectively; P<0.05). FMD was greater in control group compared with RHTN patients. Patients with UCRH had significantly impaired FMD compared with CRH (5.9±2.3% versus 7.1±5.1%; P<0.0001). Therefore, UCRH patients have less nocturnal dipping and a more impaired endothelial response compared with CRH patients. These findings suggest that important differences among patients with RHTN may allow identify subgroups with increased cardiovascular risk.
