In the Original Investigation by Gebel et al titled “Effect of Moderate to Vigorous Physical Activity on All-Cause Mortality in Middle-aged and Older Australians,” published online April 6, 2015, in JAMA Intern Med (doi:10.1001/jamainternmed.2015.0541), there were errors in the seventh and eighth sentences of the second paragraph of the Methods section. The sentences should read as follows: “Minutes per week of walking and MVPA (vigorous activity weighted by 2)33 were summed to create a total weighted amount of MVPA. The proportion of MVPA that was attributable to vigorous activity was calculated (vigorous activity × 2/weighted MVPA × 100%).” This article was corrected online.
