  • Data are means ± SD for continuous variables and n (%) for dichotomous variables. SI conversion factors: to convert glucose to millimoles per liter, multiply milligrams per deciliter values by 0.0555; to convert total, LDL, and HDL cholesterol to millimoles per liter, multiply milligrams per deciliter values by 0.0259; and to convert triglycerides to millimoles per liter, multiply milligrams per deciliter values by 0.0113.
