2.6 Statistical analysis

Statistical analyses and graph creation were done using GraphPad Prism8 (Graphpad Software Inc., USA). Normality was verified using Shapiro-Wilk test. To investigate statistically significant differences between infected and uninfected animals, ordinary one-way ANOVA with Dunnett’s correction for multiple comparisons was used. Differences between both swine subspecies were not tested because of differences at the baseline level. Data obtained in trial 1 is indicated by circles (●), data obtained in trial 2 is indicated by squares (■). Each dot represents one animal with a bar indicating mean. Statistical significance was defined as p < 0.05 and was indicated with an asterisk (*).
