Table 4 Median (interquartile range) concentrations of redox status and muscle damage biomarkers in saliva and serum in the different ages of collection (T0 = 30 days, T1 = 55 days, T2 = 115 days-old) and animals with Actinobacillus pleuropneumoniae infection (Diseased). Different superscript letters (^a, ^b, ^c) indicate p < 0.05 between ages of recollection, whereas same letters indicate p > 0.05 and the absence of letters denotes p > 0.05 across all time points. Asterisks indicate significant difference between T1 and diseased (*: p < 0.05; **: P < 0.01; ***: p < 0.001; ns: non-significant).
