^aMus m 1: mouse urinary protein; Der p 1 and Der f 1: dust mites.

^bMeasured concentrations of Bla g 1 (cockroach) were below the method detection limit in all samples.

^cSummary statistic calculated using the 2001 conversion factors (Mus m 1: 0.91; Der p 1: 0.59; Der f 1: 0.08).

^dStatistic not calculated.

^eAt this percentile, all values were below the method detection limit.
