Trigeminal Terminal Branch Neuralgias in a Headache Unit: A 15-Year Series.
Article in Journal of pain research, 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
Introduction: ICHD-3 integrates neuralgias affecting trigeminal terminal branches within broader trigeminal pain categories rather than defining them as distinct entities. In this context, their frequency and clinical characteristics remain poorly characterized. We aimed to describe their frequency and clinical characteristics in a headache unit registry. Methods: We conducted a retrospective, descriptive cohort study based on a prospective registry initiated in January 2008 at a headache unit. Patients diagnosed between January 2008 and January 2023 who fulfilled ICHD-2 criteria for nasociliary (code 13.5), supraorbital (13.6), or other terminal branch neuralgias (13.7) were included. Demographic and clinical data were collected and analyzed. Results: Among 8728 patients evaluated during the study period, 108 (1.2%) met inclusion criteria; 71 (65.7%) were women. Mean age at symptom onset was 47.4 ± 18.7 years (range 6-89), and mean time from onset to diagnosis was 34.4 ± 68.5 months (range 1-420). The most frequent neuralgias were supraorbital (39.8%) and auriculotemporal (25.9%), followed by supratrochlear (8.3%), infraorbital (7.4%), lacrimal (7.4%), mental (5.6%), nasociliary (4.6%), and infratrochlear (0.9%). Conclusion: Trigeminal terminal branch neuralgias represent a small but consistent clinical presentation defined by topographic distribution and sensory features. Recognition of these features supports anatomically guided evaluation and peripheral interventions.
