CEI, angiotensin-converting enzyme inhibitor; ARB, angiotensin-receptor blocker; CCI, Charlson comorbidity index; HPD, highest posterior density; OR; odds ratio. Notes. The posterior mean of each parameter was used as the model coefficient, and these values were expressed as odds ratios = odds ratio).
