Comparing video examinations with physical clinical examinations using finishing pigs with umbilical outpouchings as a model

Table 1 Agreement between clinical examinations performed physically in the stable or by recorded video

Clinical measurement	Veterinarian 1		Veterinarian 2		Veterinarian 3		Veterinarian 4		Mean across veterinarians

The table displays the examined continuous measured clinical signs for 102 finishing pigs with umbilical outpouchings
(a) missing value because Veterinarian 3 misinterpreted the question
*Difference: measurement at physical clinical examination minus measurement at examination performed by recorded video. SD = Standard deviation. Pearsons = Pearson’s correlation coefficient
