Frailty scales are significantly associated with age. Graph A shows the age distribution of the total study population (n = 317) by sex. In B, shown are associations of participant age with the Frailty Index, the EQ-5D-3L (EuroQol-5 Dimensions-3 Level) questionnaire, the PF (physical functioning) and HG (general health) domains of the SF-36 (short-form-36). The significance of the sex-corrected Spearman correlation coefficient is indicated in each graph. The regression line is shown in black and the shaded region represents the confidence interval
