Embargoed for 5 p.m. EDT, June 14 -- In the Annals of Internal Medicine multicenter AIDS cohort study researchers report that a concise decision tree using two tests in combination -- viral load measurements and CD4 T cell counts -- determine progression to AIDS and death from AIDS in HIV-infected individuals.
