Estimated Cox Proportional Hazard Ratios (95% Confidence Interval) of Incident Coronary Heart Disease by Quartiles of Small LDL Concentrations (NMR), Dichotomized by LDL-C (2.59 mmol/L) in 3334 Multi-Ethnic Study of Atherosclerosis Participants With Normal Fasting Glucose for an 8.5-Year Follow-Up Period

Small LDL (NMR) Quartile	LDL-C<2.59	LDL-C>2.59
1	1	1.28 (0.84–1.95)
2	0.75 (0.43–1.32)	0.963 (0.50–1.86)
3	0.841 (0.46–1.55)	1.078 (0.55–2.11)
4	1.24 (0.63–2.43)	1.58 (0.78–3.20)

Analyses were adjusted for sex, systolic blood pressure, hypertension medication use, ethnicity, age (category), high-density lipoprotein cholesterol, and log triglycerides. Quartiles in which associations reached significance (P≤0.05) are shown in the table. LDL-C indicates low-density lipoprotein cholesterol; NMR, nuclear magnetic resonance; and sdLDL-C, small dense low-density lipoprotein cholesterol.
