Model I: race, age, BMI, pack-year of smoking, hypertension, diabetes, triglyceride, LDL-C, HDL-C.
Model II-A: model II+large HDL-P.
Model II-B: model II+HDL particle size.
Model II-C: model II+VLDL particle size.
Model II-D: model II+large VLDL-P.
Model III-A: model II+large HDL-P+VLDL particle size.
Model III-B: model II+large HDL-P+large VLDL-P.
Model IV-A: model II+total LDL-P+large HDL-P+VLDL particle size.
Model IV-B: model II+total LDL-P+large HDL-P+large VLDL-P.
Reclassification categories for NRI: <5.0%, 5.0%–9.9%, 10.0%–19.9% and high ≥20%.
CRP, triglycerides, ethanol intake, large VLDL-P and medium VLDL-P were log transformed after addition of one unit. All other continuous variables were standardised.
*Per cent change in PR for race compared with model II was calculated as: ((PR for race/ethnicity in model II)–(PR for race/ethnicity in each model (model II-A to IV-B)))×100/(PR for race/ethnicity in model II).
†Model II (referent model): model I+alcohol intake+CRP+fibrinogen.
CRP, C reactive protein; HDL-C, high-density lipoprotein cholesterol; HDL-P, high-density lipoprotein particles; IDI, Integrated Discrimination Improvement;LDL-C, low-density lipoprotein cholesterol; LDL-P, low-density lipoprotein particles; NRI, Net Reclassification Improvement; PR, prevalence ratio; VLDL-P, very low-density lipoprotein particles.
