Model |
Transmission parameter estimation^{1)} |
Used data |

Basic | TP_{1} = exp (log β_{0}) |
Denmark / Netherlands |

Bivariable | TP_{2} = exp (log β_{0} + log β_{1}(ab) + log β_{2}(pIP)) |
Denmark / Netherlands |

Multivariable | TP_{3} = exp (log β_{0} + log β_{1}(ab) + log β_{2}(pIP) + log β_{3}(age)) |
Netherlands |

1) In all models log (*IP·Δt*) was used as offset variable.

ab: use of tetracyclins or β-lactams (yes/no); age: age of pigs (pre-weaning/post-weaning); pIP: infection pressure within the pen divided by total infection pressure (continuous variable).
