P-value is for comparison of CAC burden among individual coronary arteries (LAD vs RCA vs LCX vs LM) as well as between single vessel vs multi-vessel involvement.

**

P-value is for comparison of median CAC among individual coronary arteries (LAD vs RCA vs LCX vs LM) as well as between single vessel vs multi-vessel involvement.

Abbreviations: N= number of subjects, LAD= Left anterior descending artery, RCA= Right coronary artery, LCX= Left circumflex artery, LM= left main artery, CAC= coronary artery calcium, IQR= Interquartile range.
