Figure 2. Time in hospital according to frailty.

Proportion of patients who were never hospitalized, hospitalized for different intervals, and died within 1 year of transcatheter aortic valve replacement stratified on frailty groups. The percentages above bars sum to 100% for each frailty group (ie, all green bars sum to 100%). For low frailty patients, 50% survived 1 year and were never hospitalized compared with 25% of high frailty patients. In the low frailty group, 10.9% were hospitalized for >2 weeks compared with 28.1% in the high frailty group. As such, time in hospital is incrementally higher across frailty groups. The P values from χ² test are presented above bars.
