["Note: [Q1, Q3] indicates [First Quartile, Third Quartile]. MET, metabolic equivalents. “–” indicates that the sample size is too small for the value to be measured.\nThe “a” means statistically significant differences from the non-frailty period, and “b” represents statistically significant differences from the pre-frailty period. All comparisons were Bonferroni corrected. The significance level is 0.05."]
