Associations of the -2518 MCP-1 and -1607 MMP-1 two-locus genotypes and sputum conversion at more than 3 months

Two-locus genotypes	Cases n (%)	OR	Prob > chi²	95% C.I.
Group 1: A/- 1G/-	5 (9.8)	1	-	-
Group 2: A/- 2G/2G	9 (15.3%)	1.4	0.57	0.44 – 4.5
Group 3: GG 1G/-	6 (13.9%)	1.492	0.54	0.41 – 5.33
Group 4: GG 2G/2G	21 (29.6%)	3.864	0.009	1.3 – 11.5
Test of homogeneity (equal odds): Score test for trend of odds:			Chi² = 10.41, d.f. = 3; prob > chi² = 0.0154 Chi² = 8.61, d.f. = 1; prob > chi² = 0.0034

Genotype A/- 1G/- = genotypes AA 1G/1G or AA 1G/2G, AG 1G/1G or AG 1G/2G

Genotype A/- 2G/2G = genotypes AA 2G/2G, AG 2G/2G

Genotype GG 1G/- = genotypes GG 1G/1G, GG 1G/2G

n = number of cases showing sputum conversion > 3 months

OR = Odds Ratio; 95% C.I. = 95% confidence interval, d.f. = degrees of freedom
