Fig. 4.

Relative changes, percentage, in scores at different time point among non-frail and frail patients. The figure illustrates relative changes (%) in self-reported health status from baseline to discharge and four weeks after discharge among non-frail and frail patients. Self-reported health was only measured at two time points on the KCCQ and thus, not illustrated from baseline to discharge. * P < 0.05 is considered as statistically significant.
