Table 2 Global versus module-specific average properties. For each network, we show the fraction r of modules (and standard deviation) whose average degree 〈ki〉i, clustering coefficient 〈Ci〉i, and normalized clustering coefficient 〈Ci/〈Ci〉𝒟〉i significantly differ (at 95% confidence) from the global network average (see the Methods section). Fractions r>0.05 indicate that a given global property does not correctly describe individual modules. Global degree is not representative of individual-module degrees for air transportation networks. Most importantly, the global clustering coefficient is not representative of individual-module clustering coefficients for any network (except, maybe, the metabolic network of F. nucleatum).
