FIG. 3.

Cidofovir increases the survival of γHV68-infected IFN-γR^−/− mice infected with 4 × 10⁷ PFU of virus. Antiviral therapy was initiated 24 days postinfection, at which time a group of 18 mice were sacrificed; 15 of these (83%) had arteritis. Each point represents an event (death or sacrifice). The arrow indicates the day on which antiviral therapy was initiated. Asterisks represent the time points at which mice were sacrificed. P = 0.0003 for the survival advantage of cidofovir-treated mice over PBS-treated controls.
