Figure 3. IL-1β placental plasma concentration and relationship to birthweight.

Figure 3

A. IL-1β concentration in plasma sampled from blood of infected placentas with intervillositis (IV; n = 16) was higher (p = 0.017) than that of uninfected placentas (n = 31). IL-1β concentration in infected placentas without IV (n = 16) was intermediate and similar to concentrations in infected placentas with IV (p = 0.1) and to concentrations in uninfected placentas (p = 0.39). Data are represented as median (horizontal line), interquartile range (box) and 5th/95th centiles (whiskers). The ELISA was performed in duplicate. B. IL-1β concentration in plasma sampled from blood of infected placentas with intervillositis showed a negative correlation with birthweight (n = 16; Rho = −0.52; p = 0.04).
