ub: Number of unblocked reactions in the original network.

classes: Number of different reaction classes, i.e., equivalence classes w.r.t. partial coupling ⇔.

Single KOs impact: Average impact of single reaction knockouts, i.e., average number of reactions classes that become blocked by a single knockout. In brackets: Average number of reactions that become blocked (belonging to different reaction classes).

Double KOs impact: Average additional impact of double reaction knockouts, i.e., average number of reactions classes that become blocked by a double knockout {r, s}, but are not blocked by a single knockout of either r or s. In brackets: Average number of additional reactions that become blocked.

Double KOs ratio: Percentage of pairs of (uncoupled) reaction classes that have joint coupling effects. The average numbers are determined by \(\boldsymbol {\frac {1}{K}\sum _{\kappa \in K}\text {impact}\;(\kappa)}\) with K =Rep for the single, and K = {{r, s}  r, s ∈Rep with neither r
\(\boldsymbol {\stackrel {=0}{\rightarrow }}\)
s in L nor s
\(\boldsymbol {\stackrel {=0}{\rightarrow }}\)
r for the double knockouts.
