This table represents the comparison of proteins affected by a reciprocity artifact from the datasets of Gavin and coworkers [10] and Krogan and colleagues [11] as well. Before conducting the binomial test, the data graphs were restricted to the nodes common to the viable bait/prey (VBP) sets of both experiments. Again, only those proteins identified by the binomial test in which in-degree is much larger than the out-degree is compared. Both the P value and odds ratio, obtained using the hypergeometric distribution, show a strong association between the two sets of proteins.
