Headache as an extraocular manifestation of birdshot chorioretinopathy: a case series.
Article in Frontiers in ophthalmology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Birdshot chorioretinopathy (BSCR) is a type of chronic posterior uveitis with limited characterization of extraocular manifestations, including headache. We describe two HLA-A29-positive patients with BSCR who developed refractory unilateral periorbital headaches temporally associated with visual symptom onset. Headaches lateralized to the more affected eye and the patients exhibited migrainous and prominent cranial autonomic features resembling trigeminal autonomic cephalalgias (TACs) and variable responses to standard headache therapies. Together, this supports the International Classification of Headache Disorders (ICHD-3) classification as a secondary headache attributed to ocular inflammatory disease. The biological plausibility of this association is supported by trigeminal innervation of the uveal tract, providing a substrate for inflammation-driven trigeminovascular activation. Systematic studies are needed to define BSCR-associated headache prevalence, phenotype, and mechanisms and to inform diagnosis and management.
