Harnessing longitudinal information to identify genetic variation in tolerance of pigs to Porcine Reproductive and Respiratory Syndrome virus infection

Table 1 Descriptive statistics of duration (days) for each stage of infection

Stage of infection	Mean	Standard deviation	Minimum	Maximum
Early	6.90	1.32	3.01	10.60
Mid	9.19	2.11	4.04	14.87
Late	14.26	0.60	13.53	14.92
\({\text{T}}_{\rm{peak}}\)	6.90	1.32	3.01	10.60
\({\text{T}}_{ \rm{max} }\)	16.16	2.38	10.01	26.97

Early-stage is defined as initial infection (0 dpi) to \({\text{T}}_{\rm{peak}}\); mid-stage is defined as \({\text{T}}_{\rm{peak}}\) to \({\text{T}}_{ \rm{max} }\), and late-stage of infection is defined from \({\text{T}}_{ \rm{max} }\) to end of the observation period (35 dpi for trials 7 an 8 and 42 dpi for all other trials). Descriptive statistics of \({\text{T}}_{\rm{peak}}\) and \({\text{T}}_{ \rm{max} }\) are also shown. All measures are in days
