Prevalence, demographics, comorbidities, and treatment patterns of patients with the trigeminal autonomic cephalalgias: a retrospective analysis of United States electronic health records.
Article in BMC neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundThe study of the trigeminal autonomic cephalalgias (TAC) has been limited by difficulty aggregating sufficient numbers of patients. We used the Epic Cosmos electronic health record research platform to harness nationwide data from health care systems across the United States using the Epic electronic health record to analyze the prevalence, demographics, comorbid conditions and treatments for the TACs.
methodsWe queried the Epic Cosmos electronic health record database for patients with diagnoses of hemicrania continua, cluster headache, paroxysmal hemicrania, and SUNCT. Prevalences, demographics were determined from this database and comorbid conditions and treatments for these conditions were analyzed.
resultsOur study included 152,727 patients with cluster headache, 59,312 patients with paroxysmal hemicrania, 19,321 patients with hemicrania continua, and 6,291 patients with SUNCT. Five-year prevalence of cluster headache was highest (56.7 per 100,000), followed by paroxysmal hemicrania (22.0 per 100,000), hemicrania continua (7.2 per 100,000) and SUNCT (2.3 per 100,000). All four TACs showed a higher prevalence in women. Migraine was common in all four conditions and patients with cluster headache had the highest rates of nicotine, alcohol, and cannabis use disorders. Indomethacin was notably underutilized for the indomethacin-responsive TACs.
conclusionWe use a national electronic medical record database to give insight into elements of the TACs that have been previously limited by the relative rarity of these diseases.
