In the report “Variation in mineral types of uroliths from ferrets (Mustela putorius furo) submitted for analysis in North America, Europe, or Asia over an 8-year period” (J Am Vet Med Assoc 2021;259:757–763), values for the crude OR were published for the submission years of 2014, 2016, and 2018 without the tens place. The correct values are 10.37, 10.97, and 14.02, respectively. Table 2 should read as follows:
