Statistical analysis
All data were analyzed using SPSS version 23. Statistical significance level was set at P < 0.05. Mean and standard deviation were used to describe quantitative variables while percentage and frequency were used to describe qualitative variables. The normal distribution of numerical variables was checked using the Kolmogorov-Smirnov test. Independent t-test or Mann-Whitney test was used to examine the difference between two groups. Paired t-test or its non-parametric equivalent (Wilcoxon test) was used to evaluate within-group differences. Socio-demographic characteristics of the studied women were compared using independent t-test, Mann-Whitney test, and Fisher’s exact test.
