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

introductionIntracranial large artery disease (ICLAD) is a common cause of ischaemic stroke and is associated with the risk of recurrent vascular events in the short term. We compared the incidence of various long-term vascular outcomes between ischaemic stroke patients with and without ICLAD.

methodsThis was a longitudinal observational study of acute ischaemic stroke patients who were followed up serially for recurrent stroke, myocardial infarction or vascular death up to a median of 86 months. Transcranial colour-coded Doppler was used in the diagnosis of ICLAD.

resultsAmong the 581 ischaemic stroke patients studied (median age 63 ± 11 years, male 71%), 354 (60.9%) had ICLAD. In regression analyses adjusting for covariates, patients with ICLAD were more likely to have long-term composite vascular outcomes (hazard ratio [HR] 1.44, 95% confidence interval [CI] 1.02-2.03, P = 0.041), myocardial infarction (HR 2.89, 95% CI 1.71-4.91, P < 0.001) and vascular death (HR 3.52, 95% CI 1.67-7.52, P = 0.001) but not recurrent stroke (HR 1.10, 95% CI 0.72-1.70, P = 0.652), at a median of 86 months as compared to patients without ICLAD.

conclusionOur findings of poor prognostic impact of ICLAD on long-term recurrent vascular events after ischaemic stroke provide evidence for the need of specific, emphasised screening and secondary prevention, especially for coronary artery disease in this high-risk group.
