Reference groups for the binary variables include: <i>Age <3 years</i> – reference age 3–18 years; <i>CD4 <10%</i> - reference CD4 >10%, <i>Opportunistic infection</i> includes children with the presence of candidiasis, Kaposi's sarcoma, Pneumocystis jiroveci pneumonia, cryptococcosis, toxoplasmosis, or cryptosporidiosis, while the reference group did not have any of these opportunistic infections; <i>Tuberculosis at or after initiation or HIV therapy</i> – reference was the absence of HIV-tuberculosis co-infection; <i>chronic diarrhea</i> – reference children not documented to have chronic diarrhea.</p>
