Triptan Initiation and Cerebrovascular Events in Patients With Migraine: A Nationwide Cohort Study.
Observational study in Journal of the American Heart Association, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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
backgroundTriptan medications are proposed as an association of cerebral ischemic stroke in patients with migraine, but population-based data on this are lacking.
methodsA retrospective, observational, cohort study was performed using computerized claims data from a proprietary, insurance-based registry-Marketscan (by Merative). Patients with at least 1 claim related to a migraine diagnosis were included. The primary exposure was initiation of any triptan medication defined by at least 1 prescription fill. The primary end point was time to cerebral ischemic stroke. Secondary end points included time to retinal stroke (central retinal artery occlusion, other retinal artery occlusion), intracranial hemorrhage, and myocardial infarction. The association between triptan initiation and study end points was modeled using a propensity score-overlap weighted Cox model. Adjusted hazard ratios (HR) and corresponding 95% CIs were computed.
resultsIn total, 869 092 patients (median age 40.0 years [Q1-Q3, 30.0-50.0]; 77.5% female) met study selection criteria of whom 287 629 initiated a triptan and 581 463 did not. Median follow-up was 2555 days in the entire cohort. Initiation of a triptan was associated with higher hazard of cerebral ischemic stroke (adjusted HR, 2.37 [95% CI, 1.65-3.51]; absolute risk difference of 0.17% per year). Of 4 secondary end points, 2 were associated with triptan use: intracranial hemorrhage (adjusted HR, 2.37 [95% CI, 1.65-3.41]) and myocardial infarction (adjusted HR, 2.06 [95% CI, 1.60-2.66]).
conclusionsIn a population-based cohort study, initiation of a triptan was independently associated with risk of subsequent cerebral ischemic stroke.
