Cut-off value to be categorized as “frail” was set to ≥ 0.25. normal distributed data is presented as mean ± SD, non-normally distributed data is presented as median (min-max).P-values: Continuous normal distributed data were tested by t-test, continuous non-normally distributed data were tested by Mann-Whitney U test. Chi-square test was used for categorical data. Statistical significant level:P-value < 0.05. BMI, body mass index; FI score, Frailty Index score; LDL, low-density lipoprotein; HDL, high-density lipoprotein
