IFNG and mastitis: Similarly, in clinical mastitis-affected cows, no statistically significant difference of mean immunoreactive cell count numbers (%) over time was observed for IL-1α (p = 0.068, ε = 0.531), IL-4 (p = 0.125), IL-6 (p = 0.65), IL-12 (p = 0.557), IL-17A (p = 0.111), TNF-α (p = 0.374), and IFN-γ (p = 0.255, ε = 0.51).
