  1. Values are presented as mean ± SD. Effect size is presented as Cramer’s V (confidence interval) for sex and Wilcoxon effect size (confidence interval) for the other variables. Statistical analyses were performed using the chi-square test (sex) and Wilcoxon rank sum test with continuity correction (others). Education was measured as the maximum level of formal education received. MMSE was standardized according to Blesa [26]. *p< 0.05
