The impact of CGRP monoclonal antibodies on cytokine expression in chronic migraine: a cohort study.
Article in Journal of 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
backgroundCalcitonin gene-related peptide monoclonal antibodies (CGRP mAbs) are an effective preventative therapy for migraine; however, there have been rare reports of possible inflammatory complications. The primary objective of this study was to examine the impact of CGRP mAbs on immune system activation by evaluating the plasma cytokine profile of a cohort of patients pre- and post-CGRP mAb. METHODOLOGY: A prospective cohort study was undertaken at a tertiary headache service. Following informed consent and screening, the plasma cytokine profile of participants was determined using a Simoa CorPlex human cytokine 10-plex with ten targets: interferon gamma, interleukin-1β, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12p70, IL-22, and TNF⍺ prior to initiation of CGRP mAb and following 3 months of therapy. A comparator group of healthy controls at a single time point was also included.
resultsA total of 22 patients with chronic migraine and 10 healthy controls were included in the study. Administration of CGRP mAb was not associated with a significant change in cytokine expression (Wilk's lambda 0.528, p = 0.448). On post-hoc analysis, there was a significant reduction in IL-5 levels (z = - 2.321, p = 0.020) following CGRP mAb therapy.
conclusionIn this study of patients with chronic migraine, we found no evidence that treatment with CGRP mABs is associated with a significant alteration in plasma cytokine levels or shift to a Th1 phenotype.
