PT values. a Patients with MA versus controls (figure-of-eight coil); b patients with MwA versus controls (figure-of-eight coil); c patients with MA versus controls (circular coil); d patients with MwA versus controls (circular coil). Total of events in each group was the number of participants reporting phosphenes. Standard deviations in Mulleners et al. [36] were calculated from standard error and number of participants in each group (standard error × √number of participants)
