Figure 10.

Frequency curves of the full graph (‘No query’) and the five test queries, stratified by the median of the query result size; the blue, solid line represents the half of queries whose number of results rested above the median, and the red, dotted line those which fell below. For these plots, the $F_1=2\frac{\mathit{\text{Pr}}\ast \mathit{\text{Re}}}{\mathit{\text{Pr}}+\mathit{\text{Re}}}$ (protein-level) measure is used as the x-axes (note the differences in scale for the y-axes). Differences between distributions per query are statistically significant by permutation test (p ≤ 0.001), save Query D.
