Table 2 To compare \(\langle n_{ii'1} \rangle _i\) between the selected and not selected proteins when using various \(u_{\ell _1 i}\) to select proteins, P-values were computed using the t test based on the alternative hypothesis that the mean \(\langle n_{ii'1} \rangle _i\) of the selected proteins was larger that that of not selected proteins
