Correlations between AUC of the viral load and various clinical and immunological outcomes, by Spearman rank correlation coefficient. (A) Nonsignificant correlation with CD8⁺ T-cell count at the time of best viral response (n = 25). (B) Significant negative correlation with mean CD8⁺ T-cells across the follow-up period (n = 25). (C) Significant positive correlation with total days in hospital from transplant to 1 year later (n = 30). (D) Significant positive correlation with total days in hospital from first VST infusion to 6 months after infusion (n = 30). (E) Nonsignificant correlation with total days of antiviral treatment (n = 30).
