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.
Table 1
| Variable | MCI (n = 69) | NC (n = 67) | p-value | t-value |
|---|---|---|---|---|
| Sex (% male) | 20 (29.0%) | 25 (37.3%) | 0.722 | |
| Age (y) | 64.59 ± 6.66 | 64.76 ± 5.73 | 0.876 | −0.157 |
| Education level (y) | 10.78 ± 2.61 | 11.85 ± 3.04 | 0.030 | −2.199 |
Descriptive data for the general characteristics (N = 136).
Data are expressed as mean ± SD (range) except where frequencies are used for categorical data.
