Third Occipital Nerve Block and Cooled Radiofrequency Ablation for Managing Hemicrania Continua: A Case Report.
Article in Cureus, 2025. 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
Hemicrania continua is a rare and debilitating headache disorder characterized by continuous, unilateral pain that responds to indomethacin but is often resistant to other treatments. This report presents the case of a 26-year-old female patient with refractory hemicrania continua and chronic migraine who achieved significant pain relief following a fluoroscopy-guided third occipital nerve block and subsequent radiofrequency ablation (RFA) of the C2-C3 facet joint. The procedure resulted in an immediate reduction of pain as evident from a reduction in the Visual Analog Scale (VAS) score from 10/10 to 0/10, with sustained relief (VAS 2/10) at three months and notable improvement in the patient's quality of life. This case highlights the potential efficacy of targeting the third occipital nerve for the management of hemicrania continua, with thermal RFA (COOLIEF, Avanos Medical, Inc., Alpharetta, GA) offering prolonged relief by ablating nociceptive fibers. Given the emerging evidence supporting the involvement of the third occipital nerve in headache pathophysiology, the third occipital nerve block and RFA represent promising strategies for refractory cases.
