We thank Dr Degraeuwe for the opportunity to respond to his concerns regarding our study. The author states that the attending physicians might not have been blinded to the magnetic resonance imaging (MRI) results when deciding on redirection of care. Although it is true that the results of MRI were taken into consideration when making decisions on redirection of care in cohort 1, this was not the case for cohort 2. Because the predictive value and ORs are comparable between cohorts 1 and 2, this finding shows that the predictive value is reliable and not subject to a self-fulfilling prophecy.
