Like Table 1, this table also compares the proteins affected by a reciprocity artifact from the datasets of Gavin and coworkers [10] and Krogan and colleagues [11]. The only exception is that the proteins compared were those identified by the binomial tests as having out-degree greater than in-degree. Compared with Table 1, the association between the two datasets is relatively weaker in terms of both the P value and odds-ratio.
