Cytokine responses in PBMC after specific and non-specific stimulation at delivery according to gravidity. IFN-γ-secreting T cells frequencies in response to PHA and to recombinant protein DBL-5 compared primigravidae women with multigravidae women (≥two pregnancies). All box plots illustrate medians with 25th and 75th percentiles and whiskers for 10th and 90th percentiles. p values were determined by the non-parametric Mann–Whitney U test in an univariate analysis and significant differences are depicted by p < 0.05
