  1. aThe overlap (%) is with the TargetScan prediction. The number in parenthesis is the overlap (%) with TargetScan conserved predicted targets, i.e. those targets with a conserved site as predicted by TargetScan.
  2. bDifferential expression of target mRNAs in HCV+ vs. HCV- was assessed together as one group for each module. adj. p-value: adjusted p-value, estimated based on 1000 permutations.
  3. cModule p-value was estimated based on 100 simulations. P_score: the scoring method. P_Nt: the counting method.
  4. dOne representative GO term was manually selected for each module. See text for details.
