Raw scores are presented as means and standard deviations M (SD). MMSE = Mini Mental Status Examination. CVLT-II = California Verbal Learning Test-II. WAIS-III = Wechsler Adult Intelligence Scale-Third Edition. D-KEFS = Delis-Kaplan Executive Function System. Trail Making and Color-Word subtests are scored in seconds, where higher score indicates worse performance.
a Effect sizes comparing Hypertensive and Non-Hypertensive group means were examined using Cohen’s d in conjunction with independent-sample t-tests for group mean comparisons as indicated by *p < .05, ** p < .01, + p < .001.
