Cumulative sums of Z-Task Scores in TIA and migraine cohorts at first and last assessments. (a–c) Z-Task Score distributions for the TIA cohort in VGR-A, RVGR-A, and TM tasks. Dashed vertical lines indicate ± 1.96 (peripheral lines) or 0 (central line). Assessments within the first 2 weeks of symptom resolution are plotted in light grey, and those at 1 year after symptom resolution are plotted in dark grey. (d–f) The same as (a–c), but for migraineurs. Tasks were VGR-ND, RVGR-ND, and TM. Assessments within 2 weeks of symptom resolution are plotted in light grey, and assessments from 1 year after symptom resolution are plotted in dark grey.
