Table 3 Percentages and adjusted ORs (95% CI) for MetS and its related components for comparison of the three highest sdLDL-c quartiles with the first quartile

  1. ORs were estimated from Logistic regression models; Model 1 was adjustment for age, smoking, drinking and physical activity; Model 2 was additionally adjustment for FPG, hsCRP, BMI, and waist circumference based on model 1; Percentages shown in the table were unadjusted results; aThe variable used in the direct definition of the outcome variable (FPG, waist circumference or hsCRP) was excluded from the adjustment variables
