C-MoCA, mean ± SD	18.3±1.56	21.5±0.73	0.001
C-MoCA
AUC	0.72±0.10
Cutoff	20/21
Sensitivity	0.75
Specificity	0.62

The 𝑃 values were calculated using Student’s 𝑡-test for continuous variables and chi-square test for categorical variables.
C-MoCA: the Chinese version of Montreal cognitive assessment.
MMSE: mini-mental state examination.
ROC curve: receiver operating characteristic curve.
AUC: area under receiver operating characteristic curve.
