Persistence and Reasons for Treatment Discontinuation of Anti-CGRP Therapies in Migraine Prophylaxis: A Systematic Review and Meta-analysis of Real-World Studies.

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
introductionAnti-calcitonin gene-related peptide (anti-CGRP) therapies have become a mainstay of migraine prophylaxis. In routine care, treatment persistence and the reasons patients discontinue are indicators of long-term effectiveness, tolerability, and acceptability, but the available real-world evidence is fragmented across settings. We aimed to synthesize treatment persistence at 3, 6, and 12 months and to summarize the documented reasons for discontinuation.
methodsThis systematic review and meta-analysis (PROSPERO CRD420261298053) searched Embase (via Ovid) and PubMed for real-world studies with a clinical follow-up of adults receiving an anti-CGRP therapy for migraine prophylaxis with longitudinal follow-up. Persistence, defined as the proportion of patients remaining on treatment from initiation, was pooled using random-effects meta-analysis of proportions. Reasons for discontinuation were pooled descriptively. Exploratory subgroup analyses examined migraine type, drug class, and individual monoclonal antibody.
resultsFifty-three studies were included. Pooled persistence was 93.3% (95% CI 90.2-95.9) at 3 months, 84.2% (80.4-87.6) at 6 months and 76.2% (69.7-82.2) at 12 months, with substantial heterogeneity throughout (I
conclusionsApproximately three-quarters of patients remain on anti-CGRP therapy at 1 year, with most discontinuation occurring within the first six months and driven mainly by perceived lack of efficacy rather than tolerability. Marked between-study heterogeneity warrants cautious interpretation and more standardized reporting of persistence in future real-world studies.
