Statistical Analysis
Statistical analyses were performed using SPSS Statistics 22.0 software (SPSS Inc., Chicago, IL, USA) and Microsoft excel computer programs. The normality hypothesis was tested using the Shapiro-Wilk Test during data analysis. Descriptive levels are presented as means and standard deviations for normally distributed, and medians and minimum/maximum for other than normally distributed. According to normality test results, Student t and Mann Whitney U test were applied to compare first and second biopsy results. Receiver operating characteristic (ROC) curves were used to quantify the predictive accuracy of the results. Two-tailed levels of P <.05 were considered statistically significant.
