Table 1. Comparison of AUC test of GGA and MDS methods by insertion noise.

	Ins Ratio	1	2	4	6
CS	GGA-method	0.9538	0.9375	0.8964	0.8583
	MDS-method	0.7106	0.7021	0.4793	0.4580
Y2	GGA-method	0.8470	0.8013	0.7743	0.7482
	MDS-method	0.7100	0.6040	0.4276	0.4196
VM	GGA-method	0.9480	0.8956	0.8636	0.8347
	MDS-method	0.7099	0.6807	0.6913	0.6137

AUC values are computed for both methods under certain level of insertions of false positive PPIs in the original network. ‘Ins Ratio’ indicates the ratio between inserted false PPIs and the number of PPIs in the original network and corresponding AUC values are filled in the table.
