Data Presentation Error in Results Paragraph of Abstract

In the Original Investigation titled “Comparison Between Adjuvant and Early-Salvage Postprostatectomy Radiotherapy for Prostate Cancer With Adverse Pathological Features,”¹ published online January 25, 2018, there was an error in the data presented in the Results paragraph of the Abstract. In the first sentence of that paragraph, the ranges of prostate-specific antigen levels were reversed. It should read as follows: “Of 1566 patients, 1195 with prostate-specific antigen levels of 0.1 to 0.5 ng/mL received ESRT and 371 patients with prostate-specific antigen levels lower than 0.1 ng/mL received ART.” This article has been corrected online.
