Figure 2. Percent of brains with ARTAG, stratifying by age and sex, in the NACC Data set.
Pale bars represent men and darker blue bars represent women. Shown are results from the NACC Data set among autopsied subjects with ARTAG status known (n=504), sourced from 20 different independent United States Alzheimer’s Disease Research Centers. In this sample there were two general trends: ARTAG was more frequent with aging, and in males. These findings are compatible with prior results from a separate sample of research volunteers (Kovacs et al., 2018a). Error bars = stdev.
