The attribution for the cover image was inadvertently left out of the “On the Cover” subsection of the table of contents for the August 2021 issue of AJKD. The following credit line should have been included: “The photograph ‘Eclectus Parrots’ by Paul Balfe is released on Flickr under the CC BY 2.0 license.” The PDF version of the table of contents has been corrected online (https://doi.org/10.1053/S0272-6386(21)00671-5).
