Estimated fold changes as the estimates of the exponentiated effect parameter, corresponding 95% confidence intervals [], and p-values. Superscripted numbers equal the total number of OTUs belonging to the respective taxonomic group identified by sequencing amplicons generated by the Gut Microbiotassay. OTU-ratio between diarrhoeic and healthy piglets for ileum and colon, respectively, listed in parenthesis. †indicate a significant effect of interaction (Table 3). Species mark with † are not consistent findings. #Estimated fold changes for this category are calculated as: γ percentage points, where the parameter y from column 8 is the estimate of the exponential eβ of the estimated effect parameter β for diarrhoea in formula (1). The diarrhoeic percentage points range from 0 to 100.
