Covariates are listed in the order of significance as indicated by the unsigned Z-value.
*The HRs in the Cox proportional hazards model can be converted from HR per x-units (e.g., per 5 years of age above) to HR per y-units (e.g., per 1 year) using the equation: HR(y/x). For example, the HR for MACE per 1 year of age is (1.7748)1/5 = 1.1216. The same equation applies to the confidence limits. The Z test and P values are unchanged by a change of scale of the HRs.
