NOTE: Group 1: Non-hypertensives; Group 2: Hypertensive with SBP < 140 and DBP < 90 mmHg; Group 3: Hypertensive with SBP ≥ 140 or DBP ≥ 90 mmHg; SBP: Systolic Blood Pressure; DBP: Diastolic Blood Pressure; MMSE: Mini Mental State Examination; MoCA: Montreal Cognitive Assessment. The cognitive domain was considered compromised if it presented a z-score < −1.5 SD of the mean. using the normotensive group as a reference.
p values based on the Kruskal-Wallis test and Fischer's exact test.
a
significant post hoc comparisons (p < 0.05): group 1 vs. group 2.
b
significant post hoc comparisons (p < 0.05): group 1 vs. group 2 and 3.
