Incidence estimates overall (all participants and by race/ethnicity) were age- and sex-standardized to the 2010 U.S. Census population; incidence estimates stratified by sex (all men or women and by race/ethnicity) were age-standardized to the 2010 U.S. Census population.
Early AMD was defined as no AMD at baseline examination (visit 2) but the presence of early AMD at follow-up examination (visit 5).
Late AMD was defined as either no AMD or early AMD at baseline examination (visit 2) but the presence of late AMD at follow-up examination (visit 5).
Among participants with late AMD at follow-up examination (visit 5) (n=34), five participants exhibited no AMD and 29 participants presented with early AMD at baseline examination (visit 2).
