Note: BMI = body mass index, HDL-C = high-density lipoprotein cholesterol, HEI-C = Canadian Healthy Eating Index, LDL-C = low-density lipoprotein cholesterol, PROCAM = (estimated risk of major cardiac event in next 10 years), SD = standard deviation.
*Baseline characteristics were compared between patients who did and did not have the 12-month laboratory assessment using independent t test for continuous variables and the χ2 test for categorical variables.
†Although the height rounds to 1.7 m in both groups, the actual values are 1.72 and 1.68, which is a significant (p = 0.02) but not clinically important difference.
‡Metabolic syndrome criteria defined as follows: blood pressure ≥ 130/85 mm Hg or receiving pharmacotherapy; fasting blood glucose ≥ 5.6 mmol/L or receiving pharmacotherapy; triglyceride level ≥ 1.7 mmol/L or receiving pharmacotherapy; male patients with an HDL-C level < 1.0 mmol/L or female patients with an HDL-C level < 1.3 mmol/L; waist circumference as determined by a prespecified technique (Europid, white, sub-Saharan African, Mediterranean, middle eastern [Arab] patients ≥ 94 cm for men, 80 cm for women; Asian and South Central American patients ≥ 90 cm for men and 80 cm for women; white American and Canadian patients ≥ 102 cm for men, 88 cm for women.
