Estimated Cox Proportional Hazard Ratios (95% Confidence Interval) of Incident Coronary Heart Disease by Quartiles of sdLDL-C, 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

sdLDL-C Quartile	LDL-C<2.59	LDL-C>2.59
1	Ref	1.02 (0.64–1.63)
2	1.43 (0.82–2.50)	1.46 (0.82–2.60)
3	1.54 (0.85–2.80)	1.57 (0.87–2.82)
4	2.37 (1.21–4.67)	2.42 (1.32–4.44)
	P=0.012	P=0.004

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; and sdLDL-C, small-dense low-density lipoprotein cholesterol.
