Immunoglobulin isotypes concentrations in the blood of HIV-uninfected non-commercial sex workers (CSWs), HIV-uninfected CSWs and HIV-infected CSWs.
Serum immunoglobulin isotypes concentrations (ng/ml) as mean ±SEM were compared with unpaired T test for pair-wise comparisons between HIV-uninfected CSWs and the two other groups. Significance levels are shown as *(p < 0.05), **(p < 0.01), ***(p < 0.001).
