(a–c) Levels of systemic inflammatory mediators at baseline (a), mid-pregnancy (b) and delivery (c) in experimental animals stratified based upon clinical presentation (health, gingivitis, periodontitis) at each sampling interval. The bars denote the group means and the vertical brackets enclose 1 standard error of the mean. The asterisk (*) denotes significantly different from other subgroups at least at P < 0·05. The dagger (†) denotes significantly different from the control animals at the same time-point at least at P < 0·05.
