  1. SD standard deviation, n numbers, PCI percutaneous coronary intervention, DM diabetes mellitus, HTN hypertension, HD hemodialysis, UF ultrafiltration, SBP systolic blood pressure, DBP diastolic blood pressure, temp. temperature, ACEI angiotensin-converting enzyme inhibitor, ARB angiotensin receptor blocker, CCB calcium channel blocker
  2. aData presented as mean (SD) for continuous variables, and numbers with percentage for categorical variables
  3. bA P-value of < 0.05 is considered a significant difference between groups
  4. cA standardized difference of < 0.1 is considered to indicate that the difference between the groups is negligible
  5. dThe numbers are reduced because of missing data
