Table 2: Fractions of miRNA Targets of Different Node Types

Node Type Number in the Network Average of In-Degree Average of Out-Degree Number of miRNA Targets Fraction (%) P-Value
Upstream Node 59 0 4.5 8 13.6 -
Downstream Node 110 2.7 0 20 18.2 -
Cut Point 163 2.4 2.3 48 29.4 0.006*
Hub 55 19.8 22.4 19 34.5 0.015*
Intermediate Node 715 4.8 4.7 140 19.6 0.032**

Note: - represents no significant;
* and
** represent the P-values for miRNA target enrichment and less-enrichment, respectively.
