NCIt definition : The situation in which a treatment contrast (e.g., difference between investigational
product and control) is dependent on another factor (e.g., center). A quantitative
interaction refers to the case where the magnitude of the contrast differs at the
different levels of the factor, whereas for a qualitative interaction, the direction
of the contrast differs for at least one level of the factor. (ICH);
