SPSS version 15.0 was used for statistical analysis. Except
for descriptives (mean±SD, %), independent samples t test
and Chi-square test were used for comparisons of parametric
and non-parametric variables, respectively; odds ratios were
calculated via cross-tabulation, and binary logistic regression
analysis was performed with UI as dependent and DM
and other confounding variables of interest as covariates to
identify independent determinants of UI. Statistical significance
was set at 0.05 with a confidence interval (CI) of
95%. Interaction terms were built for DM and age, BMI as
well as, gravidity and parity (significance level for P
