In this study, larger rooms were significantly associated with
higher concentrations of fungi (p ¼ 0.05 and p ¼ 0.03 for univariate
and multivariate association, respectively). Significantly higher
fungi concentrations were also found in dwellings with larger area
per person (p ¼ 0.05). However, this was only true in the univariate
model. In the multivariate model, this association changed direction
and lost significance (Table 2). This could be explained as a
result of interference with variable RH in the multivariate analysis.
