Notes: Multivariate Cox regression was performed to examine the association between triglyceride levels and mortality

Data are shown in HRs and 95%CI

HR hazard ratios; CI confidence intervals

Model I adjust for none

Model II adjust for age, gender and BMI

Model III adjust for age, gender, race, education level, smoking, body mass index, systolic blood pressure, estimated glomerular filtration rate, energy, C-reactive protein, total cholesterol, high density lipoprotein cholesterol, hypertension, diabetes, and medicine using (antihypertensive drugs, hypoglycemic agents, lipid-lowering drugs, and antiplatelet drugs)
