Correction

In the November 2017 issue, the story “Predictable Response: Finding optimal drugs and doses using artificial intelligence” (Nat. Med. 23, 1244–1247, 2017) misspelled Josep Bassaganya-Riera's last name in the second mention of his work. His last name is spelled “Bassaganya-Riera” and not “Bassanganya-Riera”.
