2.3. Statistical analysis
Data were analysed using SPPS 15.0 (SPSS Inc.; Chicago, IL, USA).
Descriptive statistics are given as number of units (n), percentage
(%), mean Β± standard deviation (ππππ Β± π π). The relationships between
variables with categorical structure were evaluated by using the
Continuity Correction Chi-Square test. The Studentβs t-test was used for
the comparison of parametric continuous variables. Homogenous
distribution of data was evaluated with Kolmogorov-Smirnov test. p
<0.05 was considered as statistically significant.
