LDL discordance and HDL discordance is defined as a subject’s difference between respective baseline lipoprotein particle and cholesterol percentiles. Increasing levels of quartile discordance is denoted moving from Q1 to Q4. Abbreviations: CHD, Coronary Heart Disease; CVD, Cardiovascular Disease; LDL-C, low-density lipoprotein cholesterol; LDL-P, low-density lipoprotein particle; HDL-C, high-density lipoprotein cholesterol; HDL-P, high-density lipoprotein particle; Q, Quartile. LDL Discordance Ranges: Q1 (-86.7,-12.3); Q2 (-12.3, 0.0); Q3 (0.0, 11.9), Q4 (11.9, 78.7). HDL Discordance Ranges: Q1 (-96.9,-11.9); Q2 (-11.9, 0.4); Q3 (0.4, 12.3), Q4 (12.3, 93.1)
