Table 5

Logistic regression analysis of factors influencing radioactive iodine outcome.

	OR	95% CI
Age (per yr)	0.96	0.93, 0.99	0.015
Māori ethnicity	2.60	1.26, 5.35	0.010
Posttreatment ATD	2.19	1.06, 4.54	0.033

ATD: antithyroid medication; OR: odds ratio; CI: confidence interval.
Logistic regression model of variables shown to have in stepwise analysis. Variable of pretreatment was omitted in analysis due to estimability (near-perfect prediction of failing therapy).
