^aRegression models evaluated the mean difference in maximum grip strength and usual walking speed and the relative difference in chair stand time per year of advancing age. For standing balance the regression coefficient represents the odds of being unable to hold a tandem stand for 10 seconds per year of advancing age.
*P value <0.001.
N number, kg kilograms, m/s metres/ second, Ln(s) natural logarithm(seconds), OR odds ratio.
