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.
