Baseline GA characteristics. (A) The prevalence of moderate or severe geriatric impairments across the individual patients. Patients were sorted according to the number of impairments (ie, from 0-5 impairments), and assessments were arranged based on the prevalence of impairments in the individual domains. Moderate or severe impairments were defined as a gait speed >0.80 m/s, MNA between 8 and 11 and <7, CCI ≥ 2, GDS > 5, SMI ≤ 32.0 cm²/m² for females and ≤ 41.6 cm²/m² for males, MRA ≤ 22.0 HU for females and ≤ 29.3 HU for males, grip strength <16 for females and <27 kg for males, IADL <5 for females and <8 for females, MMSE < 24, and ADL < 5. (B) Correlation between the individual domains of the GA. The numbers in the cells denote the Spearman rank correlation coefficient (Spearman correlation coefficient ρ) (top) and the corresponding P values (bottom). The color implies the direction and strength of the correlations. A positive ρ describes a positive correlation, whereas a negative ρ describes an inverse correlation. The effect size of the Spearman rank correlation coefficient can be verbally described using the following guide for the ρ: from 0.00 to 0.10, very weak; from 0.20 to 0.39, weak; from 0.40 to 0.59, moderate; from 0.60 to 0.79, strong; and from 0.80 to 1.00, very strong. Significant P values < .005 are underlined.
