Correction to: Nature Reviews Clinical Oncology https://doi.org/10.1038/s41571-021-00527-8, published online 25 May 2021.

In the originally published article, the 95% confidence interval for patients with IDH-mutant disease with and without concurrent temozolomide was incorrect: 0.35−0.67. Instead, this confidence interval is 0.58–1.10. These values have been corrected in the HTML and PDF versions of the article.
