Treatment effect on maternal and newborn FMI across the distribution of maternal BMI at baseline.
The estimated difference in FMI between the intervention and control groups is plotted as a function of the percentiles of maternal BMI. The zero line indicates no efficacy of BEP. The positive y values indicate a higher FMI in the intervention group, and the negative y values indicate a lower FMI, with upper and lower 95% confidence bands. BMI, body mass index; FFI, fat-mass index.(TIF)Click here for additional data file.
