TVOC: sum of all volatile organic compounds measured.
–: Excluded from the model for lack of significant difference.
aOther factors included those forced into the model (age, gender, temperature and relative humidity in the living room, cigarette smoking, alcohol
drinking, time spent at home, mold cfu, Der 1, and TVOC) and those entering the model backward (listed in Table 2).
