BSA-adjusted z-scores for the coronary arteries. Coronary segments include the circumflex and distal right coronary artery in addition to the usual proximal segments (LMCA, LAD, RCA). Based on data from over 1,000 infants, children, and adolescents seen in Montreal, Quebec, Canada. Particular attention was paid to ensuring the data conforms to a normal distribution— an essential point for properly interpreting z-score results.
