Figure 3. Association of Face AI score with (A) MMSE and (B) chronological age. Face AI score correlated closely with (a) MMSE (r = −0.599, t = −16.40, p = 2.47×10−48) and relatively weakly with (b) age (r = 0.321, t = 7.44, p = 4.57 × 10−13). The Steiger’s test found the difference in correlation coefficients to be significant (p = 3.25 × 10−35).
