There are some errors on page 2 with the cut-off score for MCI based on MoCA score.

Under Methodology, in the last paragraph—5th line, there is an error, “A MoCA score of 26 or less is considered as MCI” which should read as “A MoCA score of less than 26 (25 or less) is considered as MCI.” Under Statistical Analysis—line 9, there is another error, scores “≤26” which should be “<26,” and, in Tables  3 and 4, the error is “total score (≤26)” which should be “(<26).”

Table 3: Abnormal scores on different domains of MoCA in both middle-aged (50–64 years) and elderly (≥65 years) patients with and without MCI by the European consortium criteria.

With discrete variable, the differences in the proportions were tested by chi-square tests except that *Fisher’s exact test was used to test the differences in the attention and calculation, abstraction, and memory.
