Note: Estimated standardized coefficients (β) and permutation-adjusted p-values are shown for separate linear regressions between demographic parameters age and sex (predictors) and perfusion parameters (dependent variables). Models 1 and 2 are unadjusted and adjusted for head motion and partial volume effects, respectively. M > F stands for higher mL/100 g/min in male compared to female. *p < 0.05, †p < 0.01.

ATT: arterial transit time; CBF: cerebral blood flow; CoV: coefficient of variance.
