Statistical analysis
Data were statistically evaluated using the Statistical Package for the
Social Sciences software (IBM SPSS Statistics for Windows, Version 20.0.
IBM Corp., Chicago, IL, USA). Conformity of the data to normal
distribution was assessed with the Shapiro-Wilk test and it was
determined that the data were not normally distributed. Data were
expressed as number (n) and percentage (%) and median (minimum -
maximum) values. For the categorical variables, group comparisons were
performed using the Chi-Square test. Student t test was used to evaluate
the data obtained by measuring in independent groups. In the evaluation
of categorical data in addicted groups, the McNemar test was applied.
Paired t test was used to evaluate the data obtained by measuring in
dependent groups. The level of statistical significance was accepted as
p<0.05.
