a
Independent t-test of differences between groups postintervention.
b
One-way ANCOVA for comparison of differences between control and intervention groups adjusted for baseline levels. A two-sided p-value of < 0.05 was considered statistically significant.
fT3, free triiodothyronine; fT4, free thyroxine; gw, gestational week; TSH, thyrotropin.
