(Cell 174, 758–769.e1–e9; July 26, 2018) It has come to our attention that we inadvertently swapped the headings on the two columns of Table S4. From left to right, the headings should read “No AR peak amplification” and then “AR peak amplification”. Only the headings were swapped. The manuscript reports the correct result, and the statistical tests we performed on the values (two-by-two contingency table tests) are unchanged. The error has been corrected online, and we apologize for any confusion it may have caused.
