Correlations between orthologous proteins in the S. cerevisiae and C. elegans PINs Observed rank correlations (measured by Kendall's τ) for evolutionary rates (measured with respect to S.mikatae and C. briggsae, respectively), connectivity and protein expression level (estimated by mRNA expression level in S. cerevisiae and CAI in C. elegans).

Quantity	Observed τ	95% CI
Evolutionary Rate	0.24	0.12–0.35
Connectivity	0.07	0.001–0.14
Expression	0.32	0.26–0.39
