↵a ICARS scores that significantly correlated with the data are shown. “Static,” “Dysarthria,” and “Limb” are subscores of ICARS. A Spearman correlation analysis with false discovery rate correction applied to P < .05 was performed. A multiple linear regression analysis excluding age effects was performed in the subdivisions in which the data significantly correlated with age.
↵b P < .001.
↵c P < .05.
↵d P < .01.
