There is an error in the second paragraph of the “Temperature” portion of the “Measurement of Covariates” subsection of the Methods. The correct paragraph is: For purposes of linking with REGARDS participant data, daily mean air temperature values for 2003–2009 were defined as the average of the hourly values for a 24-hour period ending at midnight local standard time. The trailing 1-year mean (°C) of the NLDAS daily mean temperatures for the grid cell containing the geographic location of the participants’ residence was used to define the temperature exposure for each participant.
