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.
