1All outcomes were scored on a scale from 0 to 3 (Table 2) but were dichotomized to ≤1 (absent, mild) or ≥2 (moderate, severe).
2Odds ratios with exact 95% confidence limits reported, with long duration (LD) as the referent.
3Two-sided P-value reported.
4Odds ratios not possible to calculate (NC).
5No lesion or gait scores ≥2 reported making evaluation of the association not possible to calculate (NC).
6Five piglets were not scored for the fourth short duration transport event at T1.
