The impact of anti-CGRP monoclonal antibodies in resistant migraine patients: a real-world evidence observational study.
Observational study in Journal of neurology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 42 papers, 4 of them syntheses that pooled it.
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
objectiveTo evaluate the frequency and headache-related impact response to monoclonal antibodies against calcitonin gene-related peptide (CGRP) in a clinical sample of refractory migraine patients.
methodsWe included migraine patients with ≥ 8 headache days/month that had failed at least three preventive medications. Demographic, medical and migraine history were collected. Patients completed an electronic headache diary including headache days/month, migraine days/month, headache pain intensity (0-3 numerical scale), use of analgesics and completed Patient-Reported Outcome questionnaires at baseline and after 12 weeks. Patients were classified into ≥ 50%, ≥ 75% and 100% responders according to the improvement in frequency.
resultsWe included 155 patients (109 erenumab and 46 galcanezumab). After 12 weeks, headache frequency decreased - 9.1 headache days/month and - 8.5 migraine days/month from baseline. A 39.5% had a ≥ 50% headache days/month reduction and a 51.6% ≥ 50% migraine days/month reduction. In the ≥ 50% migraine days/month-responders group, frequency reduction was - 13,9 migraine days/month from baseline and showed clear improvements for all patient-reported outcomes. A 14.2% and 26.5% had a ≥ 75% response in headache and migraine days/month, respectively, and 11.0% showed a 100% migraine days/month reduction. Patients who were not on other preventive medications had less severe disability and higher ratio of migraine over headache days/month were more likely of being a ≥ 50% migraine days/month-responder. We did not record any severe adverse events, being the most common constipation (20.0%), fatigue (7.1%) and a transient increase in blood pressure (5.2%).
conclusionsIn real-world clinical practice, monoclonal antibodies against CGRP proved to be effective treatments in resistant migraine patients.
