The features of late AMD, i.e., neovascular changes and geographic atrophy, are not mutually exclusive, so individuals may appear in both columns. The data for late AMD, and hence for “no late AMD”, is person-specific and therefore mutually exclusive. Those with both GA and neovascular AMD are counted in the neovascular AMD group.
