aANOVA with fixed effects of infection type and clinical study
bCMH tests stratified by clinical study.
cTwelve subjects in each group were infected with adenovirus and two with herpes simplex virus.
dFisher’s exact tests.
Only those species identified as dominant ≥ 5 times among polybacterial infections are shown.
