The authors note that the following corrections should be made to the article Body Composition, Vascular Health, Cardiorespiratory Fitness, Lung Function, Muscle Architecture, and Physical Activity in People with Young Onset Dementia: A Case-Control Study. In the Results section, the second sentence should read: Estimated VO _2max (Figure 1), lung function (Figure 2), physical activity (Figure 3), muscular architecture (Figure 4), vascular function (Figure 5), and handgrip strength (Figure 6) are displayed below. The legend for Figure 1 should read: Figure 1. Estimated VO _2max data from people with young onset dementia (n = 13) and controls (n = 11) from a submaximal Astrand-Rhyming test. Data are presented as individual dot plots with accompanying mean line. The authors apologize for any confusion this may have caused.
