LPS: lipopolysaccharide. #: all models were adjusted for parental allergy, smoking status, household density, sex, age and centre (basic). Other models were adjusted, in addition to the basic model, for the other three qPCRs, for microbial diversity based on denaturing gradient gel electrophoresis, for muramic acid, and for muramic acid, LPS and ergosterol. ¶: the table includes only those subjects (n=372) with non-missing data for all the variables adjusted.
