All statistical analyses were performed using SPSS software (IBM SPSS Statistics, version 19.0; Chicago, IL, USA). Differences in the measured data were compared using the t-test. Count data were compared using the chi-squared (χ2) test. Survival outcomes were analyzed using the Kaplan-Meier method and compared between the groups using the Log rank test. A two-tailed P value of <0.05 was considered statistically significant.
