1. *Included are all patients who initiated treatment between March 2002 and February 2008 and who attended at least two consultations.
2. †All factors with P value < 0.05 in univariate analysis were included in the multivariable regression model. P value for the likelihood ratio test for the model was <0.001.
3. aOR = adjusted odds ratio; BMI = body mass index; CI = confidence interval; OR = odds ratio; RBG = random blood glucose.
