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

Visit-to-visit blood pressure variability (BPV) is associated with cardiovascular events in the general population. Data are scarce in chronic kidney disease. We hypothesized that BPV would be associated with cardiovascular outcomes, death, and end-stage kidney disease (ESKD) and that diuretics would modify these associations in patients with chronic kidney disease. We studied US Veterans with nondialysis chronic kidney disease stages 1-5 and hypertension on nondiuretic antihypertensive monotherapy. At the time of second antihypertensive agent prescription, we propensity-matched for exposure to a loop or thiazide diuretic versus any other antihypertensive. BPV was defined as the coefficient of variation of systolic blood pressure over 6 months after second agent prescription. Cox proportional hazards regression measured associations of BPV with a primary cardiovascular event composite (fatal or nonfatal myocardial infarction or ischemic stroke; heart failure hospitalization). Secondary outcomes included all-cause death, each primary outcome component, end-stage kidney disease, and cardiovascular death. There were 31 394 participants in each group. BPV was associated with composite cardiovascular events, hazard ratio (95% CI) at second, third, fourth, and fifth versus first quintile: 1.79 (1.53-2.11), 2.32 (1.99-2.71), 2.60 (2.24-3.02), and 3.12 (2.68-3.62). Diuretics attenuated associations between the fourth and fifth BPV quintiles with composite events (
