Continuation, Resumption, and Withdrawal Rates of CGRP-mAb Treatment for Migraine Under Real-World Clinical Conditions in Which Patients Are Free to Choose Own Treatment.

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
BACKGROUND/
objectivesAnti-calcitonin gene-related peptide monoclonal antibodies (CGRP-mAbs) are effective injectable medications for the treatment of migraine. This study aimed to evaluate continuation, resumption, and withdrawal rates of CGRP-mAb treatment under real-world clinical conditions.
methodsTreatment-naïve patients with at least 3 months of follow-up after starting CGRP-mAb treatment were included. The decision to continue, discontinue, or resume CGRP-mAb treatment was made freely by the patients. Headache Impact Test-6 (HIT-6) and the Migraine-Specific Quality of Life Questionnaire (MSQ) were administered before starting treatment and one month after each CGRP-mAb injection. The endpoints were as follows: continuation rates of CGRP-mAb treatment after treatment initiation; resumption rate; withdrawal rate; changes in HIT-6 and MSQ scores; and differences in background factors between the resumption and withdrawal groups.
resultsOf the 1162 migraine patients, 146 were included in the analysis. Continuation rates of CGRP-mAb treatment at 3, 6, 9, 12, 18, and 24 months were 93.2%, 80.2%, 68.9%, 58.8%, 55.4%, and 51.7%, respectively. For the patients who discontinued, the resumption rate was 76.8%, and the withdrawal rate was 20.7%. HIT-6 and MSQ scores were significantly decreased at all assessment points compared with before CGRP-mAb treatment. There were no significant differences in factors between the resumption and withdrawal groups.
conclusionsUnder real-world clinical conditions in which patients were free to choose their own treatment, the continuation rate of CGRP-mAb treatment 12 months after treatment initiation was 58.8%, and more than half of patients remained on treatment after 24 months. The resumption rate was 76.8% and the withdrawal rate was 20.7%.
