The fungal concentrations ranged from 127.6 to 6515
CFU m2 day1 with a geometric mean of 1442 CFU m2 day1.
Table 2 shows associations between nine dwelling characteristics
and fungal concentrations. In the multivariate analysis, the amount
of fungi was significantly higher in apartments with high indoor air
relative humidity (p ¼ 0.03), room volume (p ¼ 0.03) and on higher
floor levels (p ¼ 0.02). The squared coefficient of multiple correlation
for multivariate association was relatively low (R2 ¼ 0.48,
Table 2) in this study, which means that our model does not fully
explain the variation in fungal concentrations. This can either hide
some important associations or result in false-significant results,
thus the data should be interpreted with caution.
