The calvarial bone and tissue gene pathways were determined by Pathway Express (Draghici et al. 2007; Khatri et al. 2007).

The impact factor measures the pathways most affected by changes in gene expression in calvarial bone and soft tissue to monoinfection (P. gingivalis or T. denticola or T. forsythia) and polymicrobial infection with P. gingivalis, T. denticola, and T. forsythia by considering the proportion of differentially regulated genes, the perturbation factors of all pathway genes, and the propagation of these perturbations throughout the ECM pathway.

NSI stands for not significantly impacted pathway.
