  1. Numbers and proportions (percentages) are presented corresponding to the physical status (i.e., non-frailty, pre-frailty, physical frailty) and cognitive status (i.e., no cognitive impairment, mild cognitive impairment, and dementia). Four subject groups selected for the present study are defined as follows: (a) cognitive frailty (CF), which was diagnosed in cases where both physical frailty and mild cognitive impairment criteria were met, n = 21, underlined in the table; (b) non-cognitive-impaired physical frailty (nci-PF), n = 27, bolditalics; (c) non-physically frail mild cognitive impairment (npf-MCI), n = 119, italics; (d) normal control (NC), i.e., non-physically-frail non-cognitive-impaired, n = 716, bold.
