^aSince this was a hypothesis-generating study, two thresholds were used for interpreting the results of the GLMMs. Specifically, P< 0.05 indicated that likelihood of microbial target detection and the factor were significantly associated, while a 0.05≤P<0.10 indicated the presence of a potential relationship that warrants investigation in future studies.

^bCI, Confidence interval.

^cBSC, before sample collection.
