Résumé : Results: The most important treatment attributes for patients across all three countries were time until first SRE, annual risk of renal complications and time until pain worsening. For these attributes, better levels of outcomes were significantly preferred to worse levels (p < 0.05). A 120-minutes infusion every 4 weeks was the least preferred mode of administration. Risk of ONJ was judged by patients in the UK and Germany to be the least important attribute.
