In the article entitled “AJKD Atlas of Renal Pathology: Kidney Disease in Primary Sjögren Syndrome” that appeared as an online-only article in the June issue of AJKD (Fogo et al, volume 69, issue 6, pages e29-e30), there was an error in the second sentence, where the sex ratio was inadvertently reversed. The sentence has been corrected to read “It affects 0.01%-0.1% of the population and occurs primarily from age 50 onward, with a female to male ratio of 9:1.” This correction was made to the HTML and PDF versions of the article as of June 29, 2017.
