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

backgroundAn increasing number of studies have shown an association between migraine and cardiovascular disease, in particular cardio- and cerebro-vascular events.

methodsThree electronic databases (PubMed, Embase and Scopus) were searched from inception to May 22, 2021 for prospective cohort studies evaluating the risk of myocardial infarction, stroke and cardiovascular mortality in migraine patients. A random effects meta-analysis model was used to summarize the included studies.

resultsA total of 18 prospective cohort studies were included consisting of 370,050 migraine patients and 1,387,539 controls. Migraine was associated with myocardial infarction (hazard ratio, 1.36; 95% CI, 1.23-1.51; p =  < 0.001), unspecified stroke (hazard ratio, 1.30; 95% CI, 1.07-1.60; p = 0.01), ischemic stroke (hazard ratio, 1.35; 95% CI, 1.03-1.78; p = 0.03) and hemorrhagic stroke (hazard ratio, 1.43; 95% CI, 1.07-1.92; p = 0.02). Subgroup analysis of migraine with aura found a further increase in risk of myocardial infarction and both ischemic and hemorrhagic stroke, as well as improved substantial statistical heterogeneity. Migraine with aura was also associated with an increased risk of cardiovascular mortality (hazard ratio, 1.27; 95% CI, 1.14-1.42; p =  < 0.001).

conclusionMigraine, especially migraine with aura, is associated with myocardial infarction and stroke. Migraine with aura increases the risk of overall cardiovascular mortality.
