Urinary Iodine Concentration at Baseline and Postintervention in the Mommy's Food Trial Participants
| UIC, μg/La |
Difference between groups postintervention |
|||
|---|---|---|---|---|
| Baseline, median (IQR) | Post, median (IQR) | Crude, pb | Adjusted, pc | |
| Control (n = 61) | 85 (55–130) | 73 (52–120) | 0.028 | 0.048d |
| Intervention (n = 61) | 88 (64–130) | 98 (64–145) | ||
a
Analyzed in a pooled sample of six spot samples collected on six consecutive days at each time point.
b
Independent sampled t-test for comparison of log-transformed values.
c
One-way ANCOVA for comparison of differences between control and intervention groups adjusted for baseline UIC (μg/L). A two-sided p-value of < 0.05 was considered statistically significant.
d
η2 = 0.033.
ANCOVA, analysis of covariance; UIC, urinary iodine concentration.
