HbA 1c -SD quartiles

  1. Logistic regression analysis with backward variables selection of independent correlates of any CVD event versus no CVD event. ORs of variables except HbA1c-MEAN, HbA1c-SD, and their quartiles were determined by multivariate logistic analysis from MODEL 1. The results did not change significantly in MODEL 2 and MODEL 3.
