Task: Answer Verification
Input (English): Question: Is haptoglobin phenotype a predictor of recurrence free survival in high-risk primary breast cancer patients?
Answer: In contrast to our initial results, the haptoglobin phenotype was not identified as a predictor of recurrence free survival in high-risk primary breast cancer in our validation set. Our initial observation in the discovery set was probably the result of a type I error (i.e. false positive). This study illustrates the importance of validation in obtaining the true clinical applicability of a potential biomarker.
Output (English): no
