BMI, body mass index; BP, blood pressure; HR, heart rate; LAEI, large artery elasticity index; SAEI, small artery elasticity index; P, significance of difference between means.
a
Student's t-test (all other continuous variables were evaluated using the Wilcoxon Mann-Whitney test).
b
Pearson Chi-Square test. Data missing for SAEI (N = 2), LAEI (N = 2), 1-Back Accuracy (N = 2), 2-Back 1.5 s Accuracy (N = 1) and 2-Back 1.0 s Accuracy (N = 1). P-values in bold indicate a statistically significant difference (P < 0.05) between the two groups.
