*Sample sizes are smaller when examining vessel type due to missing values. Sample sizes are 2380, 921 and 401 for the very-high HDI, high-HDI and medium-HDI groups, respectively. Furthermore, the χ2 p value is reported for each vessel type since any given patient can have multiple diseased vessels.
CAD, coronary artery disease; HDI, Human Development Indices; LAD, left anterior descending; LCX, left circumflex artery; LM, left main; RCA, right coronary artery.
