Performing ROC analysis at the best cut-off value that maximized the sum of sensitivity and specificity, Pe discriminated CRC patients based on their BRAF status with a sensitivity of 73%, specificity of 87.5%, negative predictive value (NPV) of 64% and positive predictive value (PPV) of 92% (P-value = 0.66, Fisher’s Exact Test, 95% confidence interval), while Rl showed a sensitivity of 47%, specificity of 100%, negative predictive value (NPV) of 50% and positive predictive value (PPV) of 100% (P-value = 0.62, Fisher’s Exact Test, 95% confidence interval). This evidence concerns the gene BRAF and colorectal carcinoma.
