IQR = Interquartile Range

To calculate the differenced MCDA score, each respondent’s rankings from 1 to 11 were converted into rank order centroid (ROC) weights. For each criteria, a utility weight was determined for both the chemotherapy and the no chemotherapy treatment options. Each respondent’s ROC weights were multiplied by the criteria’s chemotherapy utility weight and added together to form a chemotherapy score. The ROC weights were also multiplied by each criteria’s no chemotherapy utility weight to form a no chemotherapy score. The differenced MCDA score was calculated as the chemotherapy score minus the no chemotherapy score, rescaled from 0 to 10.
