Data are n (%) or mean ± SD. To convert HbA1c from DCCT units (%) to International Federation of Clinical Chemistry units (mmol/mol), subtract 2.15 and then multiply the result by 10.929. To convert FPG values from International System of Units (SI) (mmol/L) to conventional units (mg/dL), divide by 0.05551. To convert HDL, LDL, and total cholesterol values from SI units (mmol/L) to conventional units (mg/dL), divide by 0.02586. To convert triglyceride values from SI units (mmol/L) to conventional units (mg/dL), divide by 0.01129.
