Chemotherapy
Fifteen (24.6%) of participants with BMX finished chemotherapy before their fMRI assessments (median of 128 days before the fMRI, IQR 69.5, 173.5). Seven (11.3%) of non‐BMX participants finished chemotherapy before their fMRI assessments (median of 121 days before the fMRI, IQR 1126.5). Six (9.8%) of participants with BMX were receiving chemotherapy at the time of their fMRI assessments (starting median of 86 days from the fMRI, IQR 80.5, 90.75). Twelve (19.4%) of non‐BMX participants were receiving chemotherapy at the time of their fMRI assessments (starting median of 87.5 days from the fMRI, IQR 22.25, 156.25) (Table
