Data obtained from cases were encoded and they were transferred to the computer program. SPSS 20.0 software (SPSS Inc., Chicago, IL, USA) was used for statistical evaluation. Data distribution was tested using Kolmogorov-Smirnov test. Baseline values and 1st, 3rd month values were compared by using the repeated measure of ANOVA in intra-group evaluation and independent samples t-test in inter-group evaluation, and the significance level of p-value was accepted as 0,05 (P ≤ 0, 05). Progressions were evaluated by using repeated measures analyses of variance-ANOVA (with the Bonferroni correction) and the correlation between parameters were evaluated by using bivariate (Pearson's) correlation analysis. Positive values and negative values were considered to be correlated in the same direction and opposite direction, respectively in correlation analysis. Correlation coefficient values r ≥ |± 0.3| were accepted as correlation; and the significance level of P value that was below 0,05 was evaluated as the significant correlation.
