Statistically significant data (p<0.05) appear in boldface type. Model 1 is adjusted for age and sex. Model 2 is adjusted for age, sex, HbA1c and diabetes duration. Model 3 is adjusted for age, sex, HbA1c, diabetes duration and diabetes duration and for all other variables mentioned in table 2. Complex insulin regimen: a regimen consisting of pre-mixed insulin or combination of short-acting and intermediate- or long-acting insulin.
