Error in Institution Name in the Text

In the Original Investigation titled “Association of Maximal Extent of Resection of Contrast-Enhanced and Non–Contrast-Enhanced Tumor With Survival Within Molecular Subgroups of Patients With Newly Diagnosed Glioblastoma,”¹ published online February 6, 2020, a correction was made to remove mention of the Cleveland Clinic, which had been incorrectly named as the institution that conducted the Ohio Brain Tumor Study, and to replace the Cleveland Clinic with the University Hospitals of Cleveland among the institutional review boards listed in the Methods as approving the study. This article was corrected online.
