Length of inpatient stay. (a) Mann–Whitney U analysis of total (median) length of inpatient stay for open AAA patients in the pre- and post-CPET eras. The four bars on the right represent CPET-stratification outcomes. **P < 0.01; ***P < 0.001. (b) Mann–Whitney U analysis of total (median) length of inpatient stay for EVAR patients in the pre- and post-CPET eras. The four bars on the right represent CPET-stratification outcomes. *P < 0.05; **P < 0.01. CPET: cardiopulmonary exercise testing; EVAR: endovascular aneurysm repair; NS: not significant.
