96 (95% CI 0.93-0.99; p = 0.024). Instrumental variable analysis showed an adjusted OR of 1.00 (95% CI 0.99-1.02; p = 0.741). CONCLUSIONS Treatment strategies varied significantly between the Netherlands and Norway, with more surgery and less radiotherapy in Norway. Adjusted overall survival was better in Norway for all patients and patients less…[Read more]
