The correctly chosen model is printed in bold

aCombination of two 2-way interactions includes the correct interaction

ndiff: number of networks rejecting the additivity assumption with significant p-value for Qdiff (p<0.05), where Qdiff is the Q statistic for the difference between additive CNMA and standard NMA model
