Fig 4. Spearman rank correlations of log₂-transformed predictors (HIV reservoir measures in rows) versus log₂-transformed outcomes (HIV antibody levels in columns).

Correlation coefficients shown in each box with p-values below. Abbreviations: GP120 = envelope glycoprotein 120; GP41 = envelope glycoprotein 41; RT = reverse transcriptase; INT = integrase; PR = protease; MA = matrix; CA = capsid; rtPCR = reverse transcriptase polymerase chain reaction (PCR); ddPCR = droplet digital PCR; Alu PCR = PCR using a primer in an Alu element to detect integrated HIV-1 DNA; LTR = long terminal repeat; Gag = HIV-1 Gag protein; rCD4 = resting CD4+ T cells; PBMC = peripheral blood mononuclear cells; SCA = single copy assay.
