Table 2. Characteristics of the datasets.

outcome	:		Disease	Reference	Network inferred on
control/tumor	30∶12	97	colon cancer	[10]	The rest of the original dataset
control/tumor	50∶52	282	prostate cancer	[11]	Another dataset [31]
relapse/no relapse	69∶69	325	lung cancer	[12]	Another dataset (GSE8332)

Summary of the characteristics of each of the datasets. represents the number of individuals in the class, . The last column indicates whether the networks are inferred on an independent part of the dataset or on another dataset. In both cases, the dataset used to compute the networks is never used in the classification process.
