Weighting used to derive the relative importance scores (RIS)

*VAS = visual analogue scale; CRS = category rating scale; RIS = relative importance score. RISEU weights were based on an approximation of participants' expected utility (EU) for a decision (the expected utility of taking statins minus the expected utility of not taking statins using the probabilities shown in the table).RISPCA weights were based on principle component analysis (PCA).RISLR weights were based on logistic regression (LR).RISONE weights were equal weights (ONE).For RISEU, the estimate of the expected utility (EU) of taking statins was subtracted from the estimate of the expected utility of not taking statins.For RISPCA, RISLR, and RISONE the undesirable consequences (Pills and Cost) were subtracted from the desirable consequences (reduced risk of CHD).The formulae used to calculate the weights used for each of the four approaches to weighting (RISEU, RISPCA, RISLR, and RISONE) can be found in Appendix S1.
