| 1-3 | challenge at day 28 | 1.4 (1.1-1.9) | i: 0.93 (0.88-0.96) c: 0.96 (0.85-1.1) |
3.3 (2.7-3.9) | 4.6 (3.3-6.4) | 1.4 (1.3-1.5) |
Parameter estimates are given as posterior medians. Equal-tailed 95% credible intervals are shown between brackets. Estimates of the latent period in the combined analysis of Experiments 1-3 refer to the inoculated (i) and contact (c) birds.
