Statistical Analysis
The numeric values are shown with the mean, standard deviation, medians with ranges according to the distributions and categorical data, frequencies, and percentages. We compared the categorical variables with Chi-Square Test where applicable. We used the Student’s T-Test to compare normally distributed data and the Mann-Whitney U test for non-normally distributed data. A p-value lower than 0.05 (5% of type-I error level) was considered statistically significant in the analyses. All statistical analyses were performed using the Statistical Package for Social Science (SPSS, Chicago, IL, USA) for personal computers, version 21.0.
