TABLE 1.

Calculation of estimated probabilities of protective immunity against HTNV infection based on protection data from Figure 3.

Estimated probability of protective immunitya	HTNV PsVNA50	Lower 95% fiducial limit	Upper 95% fiducial limit
0.40	41	28	56
0.50	50	35	70
0.60	62	44	89
0.70	78	56	117
0.80	103	73	167
0.90	157	106	293

^aDetermined by logistic regression by Probit. Protection status by titer was used to calculate estimated probabilities of protective immunity.
