To the Editor:
The authors regret that there were errors in the text. This notice corrects the numbers of patients who underwent radiological examinations during the study period. We had assessed the patient number by adding up the number by each modality (e.g., CT, X-ray, MR); in doing so, we had inadvertently failed to remove duplicates across the modalities.
Content of correction:
