Survival results (Kaplan-Meier plot) of a therapeutic efficacy study in rabbits (trigger-based intervention). Animals were challenged with a target dose of 200 LD50 of B. anthracis Ames strain spores. *, survival in the group treated with 14.2 mg/kg of anti-PA IgG was significantly greater than that in the Gamunex control group (P < 0.05).
