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

backgroundVariability of blood pressure (BP) across outpatient visits is frequently dismissed as random fluctuation around a patient's underlying BP.

objectiveTo examine the association of visit-to-visit variability (VVV) of systolic BP (SBP) and diastolic BP with cardiovascular disease (CVD) and mortality outcomes.

designProspective cohort study.

settingPost hoc analysis of ALLHAT (Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial).

participants25 814 ALLHAT participants. MEASUREMENTS: The VVV of SBP was defined as the SD across SBP measurements obtained at 7 visits conducted from 6 to 28 months after ALLHAT enrollment. Participants without CVD events during the first 28 months of follow-up were followed from the 28-month visit through the end of active ALLHAT follow-up. Outcomes included fatal coronary heart disease (CHD) or nonfatal myocardial infarction, all-cause mortality, stroke, and heart failure.

resultsDuring follow-up, 1194 fatal CHD or nonfatal MI events, 1948 deaths, 606 strokes, and 921 heart failure events occurred. After multivariable adjustment, including for mean SBP, the hazard ratio comparing participants in the highest versus lowest quintile of SD of SBP (≥14.4 mm Hg vs. <6.5 mm Hg) was 1.30 (95% CI, 1.06 to 1.59) for fatal CHD or nonfatal MI, 1.58 (CI, 1.32 to 1.90) for all-cause mortality, 1.46 (CI, 1.06 to 2.01) for stroke, and 1.25 (CI, 0.97 to 1.61) for heart failure. Higher VVV of diastolic BP was also associated with CVD events and mortality. LIMITATION: Long-term outcomes were not available.

conclusionHigher VVV of SBP is associated with an increased risk for CVD and mortality. Future studies should examine whether reducing VVV of BP lowers this risk. PRIMARY FUNDING SOURCE: National Institutes of Health.
