title: Erratum.
abstract: In the article entitled "Treatment of Nontraumatic Rotator Cuff Tears: A Randomized Controlled Trial with Two Years of Clinical and Imaging Follow-up" (2015 Nov 4; 97[21]: 1729-37), two footnotes in Table VI were incorrectly transposed. Specifically, "The values are given as the number of shoulders, with the percentage in parentheses. The values are given as the mean and the standard deviation." should have read "The values are given as the mean and the standard deviation. The values are given as the number of shoulders, with the percentage in parentheses."
