Comparison of frequencies of interleukin-1 receptor antagonist alleles in children with community-acquired pneumonia–induced ALI/ARDS

	Presence or absence of ALI/ARDS
Copies of the A1 allele	No ALI/ARDS, n (%)	ALI/ARDS, n (%)
2, n = 549	522 (74.6)	27 (61.4)
1, n = 171	158 (22.6)	13 (29.5)
0, n = 24	20 (2.9)	4 (9.1)^a

p = 0.023 by chi-square analysis.

ALI, acute lung injury; ARDS, acute respiratory distress syndrome.
