Table 3.

Frequency of the CCR5 Δ32 heterozygous genotype among human immunodeficiency virus type 1 (HIV-1)–uninfected and HIV-1–infected women, stratified by CD4⁺ cell count at entry.

HIV-1 status	No. of subjects	Participants heterozygous for Δ32, no. (%)	OR	Exact 95% CI	Exact P^a
Uninfected	542	45 (8.3)	1	NA	NA
Infected, CD4⁺ cell count, cells/μL
<200	593	29 (4.9)	0.57	0.34–0.94	.027
200–349	458	18 (3.9)	0.45	0.24–0.81	.007
350–499	403	30 (7.4)	0.89	0.53–1.47	.718
≥500	518	28 (5.4)	0.63	0.37–1.05	.082

NOTE. CI, confidence interval; NA, not applicable; OR, odds ratio.

Test for trend. P = .012 (χ² test); P = .307 (χ² test) among HIV-1–infected categories only.
