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

backgroundWhite matter hyperintensities are the commonest manifestation of cerebral small vessel disease, associated with stroke, functional impairment, and cognitive decline. They are commonly preceded by hypertension, but the magnitude and clinical importance of this association is unclear.

aimsQuantify the relationship between blood pressure and white matter hyperintensities across studies.

methodsPubMed and EMBASE were searched for studies reporting associations between concurrent or historic blood pressure and white matter hyperintensities. Beta coefficients from linear models were extracted, whether standardized, unstandardized, unadjusted or adjusted for age, sex, and cardiovascular risk factors. Beta-coefficients were combined by fixed and random effects meta-analysis, combining standardized beta-coefficients or unstandardized coefficients measured by consistent methods.

resultsTwenty-five of 3230 papers were eligible, including 53,392 participants. Systolic blood pressure was significantly associated with white matter hyperintensity volume (WMHV) after maximal adjustment (standardized beta 0.096, 95%CI 0.06-0.133, p < 0.001, I

conclusionsA standard deviation increase in SBP is associated with 10% of a standard deviation increase in WMHV, providing the current best estimate of the potential reduction in progression of white matter hyperintensities expected with good control of blood pressure.
