Best Fit Dose-Response Model.

aIn exponential dose-response model, R is used as virulence coefficient, while in beta-Poisson dose-response model, the ratio of α/β is used as virulence coefficient.bThe distributions are fitted to bootstrap samples of dose response parameters using @RISK [62].cThe intestinal risk is replaced by cutaneous risk since the fractions of inhalational anthrax and cutaneous anthrax were the same in the 2001 anthrax letters attacks [6].dThe data for 2.1 µm particles are used.eThe data for 4.5 µm or less in diameter are used.fThe data for the age group of 5 days and above are used.
