In the original article, there were mistakes in Table 1 and Table 2 as published. Due to the negligence of the inputter, the standard deviation of MMSE in MCI group in Table 1 was wrong. These values should instead be 25.87 ± 1.07. The MMSE and MoCA data should also be removed from Table 1, and instead placed in Table 2. Additionally, Table 2 incorrectly showed the data calculation results of 64 patients with MCI and 30 patients with NC. The corrected Table 2 shows the 69 patients with MCI and 67 patients with NC, and the N value is 136. The corrected Tables 1 and 2 appear below.
