Mother and cord blood antibody levels (log₁₀ MFI) in HIV-positive and HIV-negative women. Boxplots illustrate the medians and the interquartile range for IgG (A), IgG1 (B), IgG2 (C), IgG3 (D), and IgG4 (E) subclasses in HIV-positive (red) and HIV-negative women (blue). Levels between groups were compared by Wilcoxon-Mann–Whitney test and p-values were adjusted for multiple testing by the Benjamini-Hochberg approach (False Discovery Rate 5%). Statistically significant differences are highlighted with an asterisk.
