Impact of pregnancy status on subgingival plaque total bacterial carriage. (A) Mean difference of total bacterial carriage in subgingival plaque between different trimesters of pregnancy. (B) Mean difference of total bacterial carriage in subgingival plaque between pregnancy and postpartum. (C) Mean difference of total bacterial carriage in subgingival plaque between pregnant women and non-pregnant women. Study heterogeneity (I2) and the related p value were calculated using the continuous random effect methods. The Mean Difference, 95% CI of each study included in the meta-analyses and forest plots of comparisons shown in A-1 through C-3 indicate that, regarding total bacterial carriage in subgingival plaque, there is no statistically difference between each stage of pregnancy (p > 0.05), between postpartum and pregnancy (p > 0.05), and between non-pregnant and pregnant women (p > 0.05).
