Comparison of virulence parameters
| Molecular subgroups compared | r value difference (log)a | Confidence interval (95%)a |
|---|---|---|
| inlA without PMSC vs inlA with PMSC | 2.55 (3.24) | 1.91-3.20 (2.62-3.86) |
| inlA without PMSC vs inlA with PMSCNot4 | 0.76 (1.40) | −0.48-1.99 (0.18-2.26) |
| inlA without PMSC vs inlA with PMSC4 | INFb (4.06) | NAN-INFb (3.38-4.73) |
a
Values were obtained based on human illness and clinical isolate data from the MD and CA FoodNet sites(not in parentheses) and from multiple U.S. states(in parentheses).
b
INF, infinite; NAN, not a number. These outputs were obtained in simulation because the number of cases could be 0 in the distribution of the number of cases attributed to isolates with inlA PMSC4.
