^aDetection rate represents the percentage of fecal samples that contained specific bacterial groups/genera/species above the detection threshold.

^bMeans and standard deviations are indicated.

^cStatistical differences were examined using the Mann-Whitney U test.

^dq values were calculated using the Benjamini and Hochberg method.

^eStatistical differences were analyzed using Fisher’s exact test.
