Error in Methods

The Original Investigation “Association of Plasma p-tau181 and p-tau231 Concentrations With Cognitive Decline in Patients With Probable Dementia With Lewy Bodies,”¹ published in the January 2022 issue of JAMA Neurology, had an error in the Statistical Analysis subsection of the Methods. The last sentence of that subsection should read as follows: “All P values from 1-sided and 2-sided tests were deemed statistically significant at P < .05.” This error has been corrected; this article was also corrected on December 6, 2021, to fix a typographical error in the Key Points.
