  1. P values indicate the significance of the association to MACE.
  2. NOTE: The data are presented with median and interquartile range (IQR) or percentage (%).
  3. Legend: MACE (major adverse cardiac event), ASA (American Society of Anesthesiology), BMI (Body mass index), RCRI (revised cardiac risk index), COPD (chronic obstructive pulmonary disease), AMI (acute myocardial infarction), AF (atrial fibrillation), ACE (angiotensin-converting enzyme), AR (angiotensin receptor).
  4. 1 P value derived using Mann–Whitney U test. 2 P value derived using Chi-squared test for quantitative variables. 3 P value derived Fisher’s exact test for qualitative variables.
