(a) Nasal total leucocyte counts; values are median (lower and upper quartile),×105/mL
0	0.0 (0.0, 5.5)	0.0 (0.0, 4.8)
2	11.9 (0.0, 28.5) *	0.0 (0.0, 4.6)

17	6.9 (0.8,12.9)	0.0 (0.0, 0.8)
(b) Change from baseline in neutrophil counts in nasal lavage in subjects with colds; values are median difference (inter‐quartile range)×104/mL
2	5.4 (0.0,11.0)	0.0 (−1.1, 2.2)
4	2.6 (0.0,7.9)	1.8 (−1.3, 9.7)

EVW=exclusive viral wheezers; number of observations on days 2, 4 and 17, respectively: viral wheezers 16, 16, 13; controls 9, 9, 6. No differences between EVW and controls were significant (Mann–Whitney U‐test). Difference from baseline:

^* P=0.026,

^** P=0.027.
