Models adjusted for age and gender of the participants, visits, season of sampling, place sampled in the home (for overall), location of the house (farm or non-farm, except in stratified analysis by this variable), family income, smoking in the house, presence of central air conditioning, presence of pets in the house, and main heat source.
Abbreviations: df, degree of freedom; EU, endotoxin units; CBB, child bedroom bedding; CBF, child bedroom floor; PAF, play area floor; KNF, kitchen floor. Bold indicates significant changes (p-value < 0.05).
