Statistical analysis The continuous variables will be analyzed using the Student's t-test and analysis of variance (ANOVA). Data will be presented as mean ± 1 SD for continuous variables and as frequencies for categorical variables. The chi-squared test will be utilized for the comparative study between the groups in use of vildagliptin with those in use of glibenclamide. Logistical regression will be performed for associations with statistical significance. An alpha error of 5% was considered acceptable giving significance with p-value<0.05.
