Multivariate linear regression analysis of s₁ for CD4 and CD8 T-cell subsets with baseline CD4 T-cell count and baseline VL (log₁₀) as covariates

CM indicates central memory; EM, effector memory; and Act, activated.

One patient with very high naive CD8 T-cell estimate for s₁ (38-fold higher than the average, statistically an outlier) was excluded from the CD8 naive analysis. Significant association with the VL is lost with the inclusion of this outlier.

One patient with very high effector memory CD4 T-cell estimate for s₁ (24-fold higher than the average, statistically an outlier) was excluded from the CD4 EM analysis. Significant association with the VL is lost with the inclusion of this outlier.
