The Comorbidity-Age Index was developed with age ≥ 40 years as a threshold to add a point to the HCT-CI. Because the impact of age has likely changed over time, we tested the index with the original age threshold (Comorbidity-Age[40] Index) and with age ≥ 60 years as a threshold (Comorbidity-Age[60] Index).
