  1. MPCAD = more peripheral coronary artery disease, LMCAD = left main coronary artery disease
  2. *Statistical tests performed: Student's t-test or its non-parametric equivalent Mann-Whitney U test was used for comparison of continuous data - Pearson's chi-square test was employed for comparison of categorical variables.
  3. Data are expressed as mean ± standard deviation (SD) or as median and interquartile range (IQR) according to normality of continuous variables. All qualitative variables are presented as absolute and relative frequencies.
