hA3G mRNA expression in ES after one year ofexposure. Left panel. hA3G mRNA expression in exposed seronegative subjects at time of diagnosis of their partners, and after one year of follow up. There was a significant decrease (p = 0.0022, Wilcoxon sign test). The inset box plot is healthy control expression level, for reference purposes only. Right panel. Viral load in the partners of the ES subjects after a year of treatment. The overall reduction was also significant (Wicoxon's sign test p = 0.018).
