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

objectiveTo determine whether there is an association between previous migraine and cryptogenic TIA or ischemic stroke at older ages.

methodsWe determined the age-specific associations of history of migraine and Trial of Org 10172 in Acute Stroke Treatment (TOAST) subtype of TIA and ischemic stroke in a population-based cohort study (Oxford Vascular Study; 2002-2012).

resultsAmong 1,810 eligible patients with TIA or ischemic stroke, 668 (36.9%) had cryptogenic events, of whom 187 (28.0%) had previous migraine. Migraine was more commonly associated with cryptogenic events than with those of known etiology (odds ratio [OR] 1.73, 95% confidence interval [CI] 1.38-2.16, p < 0.0001; cardioembolic 2.00, 1.50-2.66, p < 0.0001; large artery 1.75, 1.20-2.53, p = 0.003; small vessel 1.32, 0.95-1.83, p = 0.096). The association of migraine with cryptogenic events was independent of age, sex, and all measured vascular risk factors (RFs) (adjusted OR 1.68, 1.33-2.13, p < 0.0001) and was strongest at older ages (<55 years, OR 1.11, 0.55-2.23; 55-64 years, 1.48, 0.83-2.63; ≥65 years, 1.81, 1.39-2.36) and in patients without vascular RFs (0 RFs OR 2.62, 1.33-5.15; 1 RF 2.01, 1.35-3.01; 2 RFs 1.80, 1.21-2.68; 3 RFs 1.21, 0.71-2.07; 4 RFs 0.92, 0.28-2.99). Results were consistent for migraine with or without aura and for analyses excluding TIA or stratified by sex or vascular territory of event.

conclusionsIn this population-based study of stroke etiology stratified by age, migraine was most strongly associated with cryptogenic TIA and ischemic stroke, particularly at older ages, suggesting a causal role or a shared etiology.
