KM curve for MMSE categories and mortality: a. MMSE groups: 27 points and higher, 24–26 points, 23 points and lower. b. MMSE groups: age and education adjusted normal cognitive function and cognitive impairment. c. MMSE groups: 27 points and higher, 26 points and lower (modified cut-off value). Legend: In Fig. 1/A log-rank pairwise comparison was performed: an MMSE score of 27 points or higher vs. 24–26 points, p = 0.531; 27 points or higher vs. 23 or fewer points, p = 0.007; 24–26 points and 23 points and below, p = 0.120
