Correction: Use of radiographic measurements to diagnose stage B2 preclinical myxomatous mitral valve disease in dogs

In the article “Use of radiographic measurements to diagnose stage B2 preclinical myxomatous mitral valve disease in dogs” (J Am Vet Med Assoc 2020;256:1129–1136), incorrect values are reported in the text for the combined variable of vertebral heart size and vertebral left atrial size (VHS + VLAS) at the cutoff that resulted in maximum specificity and for the positive predictive value (PPV) at that cutoff. The correct value for the VHS + VLAS cutoff that resulted in maximum specificity is 14.75 vertebral body units (VBUs), and the PPV at that cutoff is 93%. The values reported in Table 3 are correct.
