Continuous variables are presented as mean ± standard deviation if normally distributed and median (interquartile range) if not normally distributed. LMT, left main trunk; LAD, left anterior descending artery; LCX, left circumflex artery; RCA, right coronary artery (RCA); OM, obtuse margin (OM) branch; PDA, posterior descending artery branch.
