P = 4.1 × 10-2

Odds ratio = 2.17

Like Table 3, this table also compares the proteins affected by a reciprocity artifact from the datasets of Gavin and coworkers [10] and Krogan and colleagues [11] restricted to the common viable bait/prey (VBP) proteins. We consider those proteins identified by the binomial test in which the out-degree is much larger than the in-degree. We again see that the association between the proteins sets in terms of P value and odds ratio is weaker when compared with the association obtained from Table 3.
