Notes. LCA 1 & 2 are characterized by three different medications each. LCA 3, 4, and 5 are characterized by single medications. Percentages in bold denote percentage of sample assigned to each latent class. Italics denote item-response probabilities of ART medications that were most divergent among latent classes and used to define each latent class.
