From: Biosecurity level and health management practices in 60 Swedish farrow-to-finish herds

	Gender of person responsible for biosecurity in farrowing unit: female (upper row) or male (lower row)			Herd size: smaller (upper row) or larger (lower row)			Years of experience: less (upper row) or more (lower row) than 23 years			Conventional herd (upper row) or outdoor production (lower row)			Conventional herd (upper row) or satellite herd (lower row)			Conventional herd (upper row) or SPF herd (lower row)			Responsible person education level basic – lower (upper row) or higher – university (lower row)

Overall scores and subcategory scores between herds with a female versus male caretaker of piglets and sows (female n = 28, male = 31), smaller (96–185 sows, n = 30) and larger herds (190–1200 sows, n = 29), farmers with <23 years (range 5–22 years, n = 30) of experience and farmers with ≥23 years (range 23–41 years, n = 29) of experience, conventional herds (n = 34) and outdoor production (n = 3), satellite herds (n = 19) and SPF herds (n = 3) and lower (n = 26) and higher education level (n = 30) for personnel among 60 Swedish farrow-to-finish herds. The significance of differences between groups was assessed by Mann–Whitney test. Significant P-values are indicated by bold characters.
M = medians, IQR = Interquartile range, a = statistical analysis not possible due to data missing, b = n is 2, np = not possible to calculate IQR.
