Figure 2 Prevalence of metabolic syndrome and contributing factors by plasma triglyceride concentration in cases (A) and control subjects (B). The legend shows triglyceride strata (mg/dl). Cut points for factors of the metabolic syndrome are as defined by ATP-III except body mass index (BMI) which for this study was defined as BMI 30 kg/m2. All trends were significant with p < 0.0001 except for the high blood pressure (BP) in cases for which the p value for trend was 0.002. Patients with type III hyperlipidemia were excluded. HDL = high-density lipoprotein.

Figure 3 Odds ratios of premature coronary artery disease in triglyceride (TG)/high-density lipoprotein (HDL) categories and by hypertension. Odds ratios for normal blood pressure (NBP), high HDL, high TG and low HDL, low TG categories were significant at p = 0.006 and 0.0010 respectively. All others are significant at p <0.0001. HBP = high blood pressure.

Figure 4 Summary of coronary artery disease risk (odds ratios and 95% confidence intervals) associated with commonly used cut points. Risks were estimated simultaneously in a multiple logistic regression model adjusting for age, gender, hypertension, diabetes, serum albumin, bilirubin, creatinine, and low-density lipoprotein cholesterol. HDL = high-density lipoprotein; TG = triglycerides.
