Age differences in secular trends in black-white disparities in mortality from systemic lupus erythematosus among women in the United States from 1988 to 2017.

Black adults, youths and adolescents had four to seven times higher SLE mortality rates than their white counterparts and the black-white disparities persisted during the past three decades. On the contrast, black women had less than two times higher all-causes mortality rates than their white counterparts and black-white disparities significantly diminish during the past three decades.
