Genital soluble HLA-G levels in HIV-1-uninfected CSWs, HIV-1-infected CSWs, and HIV-1- uninfected non-CSW women according to the HLA-G gene polymorphism.

CSW, commercial sex worker; HIV-1, human immunodeficiency virus type 1; I, insertion,
N, number of participants; NS, nonsignificant; SD, standard deviation; SNP, single nucleotide polymorphism; UTR, untranslated region.
Data are mean (SD).
aP-values for the comparison between all groups were calculated with one-way analysis of variance test.
bP-values were calculated with Mann-Whitney U test.
cPresence of the allele in the homozygous or heterozygous states.
dP = 0.051 for the comparison between HIV-1-uninfected CSWs and HIV-1-infected CSWs, P = 0.153 for the comparison between HIV-1-uninfected CSWs and HIV-1-uninfected non-CSWs and P = 0.002 for the comparison between HIV-1-infected CSWs and HIV-1-uninfected non-CSWs as determined by Mann-Whitney U test.
ePresence of the variants in the homozygous state.
