Other related information
To verify the difference of patological complete response (pCR) between mutant type and wild type of TP53 signature using Fisher's exact test. Performance of TP53 signature against pCR will be evaluated using sensitivity, specificity, positive predictive value, and negative predictive value. Recurrence-free survival will be estimated using the Kaplan-Meier method, and the log-rank test will be used to test whether recurrence-free survival is different between mutant and wild types of TP53 signature.
