Error in Methods Section

There were several words missing from the first sentence of the Methods section of the Research Letter titled “Increase in Prostate Cancer Distant Metastases at Diagnosis in the United States,” by Hu et al.¹ The sentence should have read “Using the most recent Surveillance, Epidemiology, and End Results (SEER) release, we identified 1 107 111 men 40 years or older diagnosed with pathologically confirmed prostate cancer and 545 399 from 2004 to 2013.” The article has been corrected online.
