Intervention Effect | 0.28, p=.798 | 0.17, p= .700 | 0.23, p=.781 |
All p-values are one-sided, to detect a decrease in BMI in tribes receiving the community+family intervention relative to the tribe receiving only the community intervention.
Change from birth to 24m, compared to tribe A, adjusted for PedNSS data as described in the text, and adjusted for baseline values
