Results: Patients given a single dose of I of 600 MBq (16 mCi) (N = 485) had a higher cure rate (84.1%) compared with those receiving either 370 MBq (10 mCi) (74.9%, P < 0.001) or those given 185 MBq (5 mCi) (63%, P < 0.001). An increased incidence of hypothyroidism by 1 year was evident with higher doses (600 MBq: 60.4%; 370 MBq: 49.2%, P = 0.001; 185 MBq: 38.1%, P < 0.001). Binary logistic re...
