MoCA-C: Chinese version of Montreal Cognitive Assessment

Early 60s represents ages between 60 and 64 years; late 60s represents ages between 65 and 69 years; early and late years are similarly separated for the 70s and 80s age groups.

*Significant difference compared with the early 60s group (* P < 0.05, ** P < 0.01).

† Significant difference compared with the late 60s group (^††P < 0.01).

x Significant difference compared with the early 70s group (^xxP < 0.01).

⧫ Significant difference compared with the late 70s group (^⧫P < 0.05, ^⧫⧫P < 0.01).

× Significant difference compared with the early 80s group (^×P < 0.05, ^××P < 0.01).

▴ Significant difference compared with women (^▴P < 0.05, ^▴▴P < 0.01).
