The values are compared between groups using the one-way ANOVA. O+IT* Differences between O+IT versus IT* alone are significant, with a p value <0.001, due to a change in the use of combined drugs. HbA1c** mean HbA1c in each age groups.
Diet*, treatment of diabetes; IT, insulin treatment; O, oral hypoglycaemics agents.
