Models derived from in vitro analyses of spleen, liver, and lung leukocyte functions predict vaccine efficacy against the Francisella tularensis Live Vaccine Strain (LVS).

The differences between the vaccine groups for the variable w are indicated as positive and nonsignificant (+, i.e., a positive difference between the group sample means but for which P was >0.05) or negative and nonsignificant (−, i.e., a negative difference between the group sample means but for which P was >0.05), positive and significant (*, P ≤ 0.05), or positive and highly significant (**, P ≤ 0.01).
