Table 4 Associations of the respective domains of the GAS, GDS and MMSE tests with subject membership in clusters.

HF – highly functional; CI – cognitive impairment; CF – cognitive frailty; PhyF – physical frailty. ^* Differences in mean values shown only for tasks (questions) on the MMSE, for which any differences were observed among the clusters. For two memory-related functions: “repetition” and “delayed memory”, maximum point scores were 2 and 1, respectively; the maximum point scores were 5 each; for two non-memory-related functions: “orientation in time” and “attention”, the maximum point scores were 5 each.
