Descriptive statistical analysis was performed on all variables. Multivariate logistic regression analyses were performed to test the possibility of association between the outcome measures and duration of disease. The independent variables were age, gender, BMI (body-mass index) category, current prescription, drug insurance coverage, glycemic management, lifestyle, number of co-morbidities and compliance to recommendations/therapy. All statistical analyses were conducted using SAS software. A p value <0.05 was considered statistically significant.
