FIG. 1.

Plasma SIV and CMV load and CD4⁺ T-lymphocyte counts in SIV-infected rhesus macaques with or without CMV disease. (a) Box plots comparing levels of plasma SIV RNA, plasma CMV DNA, and CD4⁺ T-lymphocyte counts at the time of death in six SIV-infected rhesus macaques with CMV disease (YES) and five SIV-infected rhesus macaques without CMV disease (NO). Horizontal bars show median values, boxes indicate 75% confidence intervals, and error bars show 95% confidence intervals. P values were determined by the nonparametric Mann-Whitney U test. (b) Correlation between time post-SIV infection and plasma SIV RNA, CMV DNA, and CD4⁺ T-lymphocyte counts. (c) Correlation between CMV load and SIV load or CD4⁺ T lymphocytes. Correlation coefficient (Rho) and P values were determined by the Spearman rank correlation coefficient test.
