To the Editor: Dr Stagnaro-Green and colleagues1 argued that a randomized controlled trial (RCT) of iodine in pregnancy would be unethical because many international bodies recommend additional iodine intake, largely for the prevention of cognition-related adverse effects in offspring. We dispute their assertion that such a trial is necessarily unethical.
