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

backgroundMost intracerebral hemorrhages (ICH) are caused by 1 of 2 cerebral small vessel diseases (cSVDs): arteriolosclerosis and cerebral amyloid angiopathy (CAA). Hypertension is a major risk factor for ICH, but its contribution to the hemorrhagic manifestations of these arteriopathies remains uncertain. We investigated associations between a cardiac structural biomarker of systemic hypertension (left ventricular mass [LVM]) and cSVD neuroimaging phenotype in patients with ICH.

methodsWe assessed brain magnetic resonance imaging and echocardiography cross-sectional data from patients with symptomatic hemorrhagic cSVD, including macroscopic ICH, convexity subarachnoid hemorrhage, or cognitive impairment. We compared LVM in patients with possible or probable CAA, mixed pattern cSVD, or arteriolosclerosis. We used linear regression models to investigate associations between LVM, patient characteristics, and SVD.

resultsWe included 216 patients (104 with CAA, 91 with mixed pattern cSVD, and 21 with arteriolosclerosis). Patients with CAA had a significantly lower mean LVM (148.8±44.9 g) compared with those with mixed pattern cSVD or arteriolosclerosis (172.8±59.3 g) (

conclusionsOur findings suggest cardiac structure relates to the neuroimaging phenotype of symptomatic hemorrhagic cSVD, including ICH. This is relevant to the classification, understanding, and prevention of hemorrhagic cSVD.
