Estimated Cox Proportional Hazard Ratios (95% Confidence Interval) of Incident Coronary Heart Disease by Quartiles of sdLDL-C, Nuclear Magnetic Resonance–Derived Small LDL Particle Concentrations, and LDL-C in Multi-Ethnic Study of Atherosclerosis Participants With Impaired Fasting Glucose or Diabetes Mellitus (n=1048^*, 84 events) for an 8.5-Year Follow-Up Period

Quartile	LDL-C (0.31–8.15 mmol/L)	Small LDL-P (0–2299 nmol/L)	sdLDL-C (0.003–4.3 mmol/L)
1	Ref	Ref	Ref
2	0.91 (0.49–1.70)	0.89 (0.44–1.83)	1.06 (0.56–2.01)
3	1.15 (0.62–2.12)	0.66 (0.30–1.48)	0.75 (0.37–1.57)
4	1.15 (0.61–2.19)	0.90 (0.40–2.02)	1.06 (0.50–2.23)

Ranges for each analyte are specified. 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; LDL-P, low-density lipoprotein particle; and sdLDL-C, small dense low-density lipoprotein cholesterol.
