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

The association between blood pressure variability (BPV) and the risk of all-cause mortality and cardiovascular diseases (CVD) is not well understood. The Kailuan study is a prospective longitudinal cohort study on cerebrovascular events and cardiovascular factors. In this study, resting blood pressure was measured at baseline and every 2 years from 2006 to 2007. BPV is mainly defined as the coefficient of variation (CV). Hazard ratio (HR), with 95% confidence intervals (CI) was calculated using Cox regression model. Among 52 387 participants, we identified 1817 who ended up with all-cause death and 1198 with CVD. Each 4.68% increase in BPV was associated with a 13% increase in the risk of mortality (HR = 1.13, 95% CI = 1.09-1.18) and a 7% increase in CVD (HR = 1.07, 95% CI = 1.02-1.13), respectively. After adjustment of confounding factors, the HR of comparing participants in the highest versus lowest quartile of CV of systolic blood pressure (SBP) was 1.37 (1.19, 1.57) for all-cause death, 1.18 (1.01, 1.39) for CVD. Similar results were also observed when BPV was measured by different parameters. We concluded that visit-to-visit BPV was associated with all-cause death and cardiovascular and cerebrovascular events in Chinese general population.
