In search of a gold standard patient-reported outcome measure to use in the evaluation and treatment-decision making in migraine prevention. A real-world evidence study.
Abstract
Patient-Reported Outcomes (PROs) have been developed to numerically quantify disability, impact and quality of life. They have been widely used in migraine clinical trials. However, we still do not know which PRO more accurately reflects preventive treatment response from a patient's perspective or which one may help us with treatment decisions in clinical practice. They have been used to enforce the efficacy results in clinical trials and real-world evidence so far. The aim of this study was to analyze which PROM is (1) better correlated with all primary efficacy endpoints and (2) which one is better associated with treatment continuation with CGRP-mAbs at week-12, which is usually the moment when this decision is made.
