Treatment effect on maternal and newborn FFMI across the distribution of maternal BMI at baseline.
The estimated difference in FFMI 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 FFMI in the intervention group, and the negative y values indicate a lower FFMI, with upper and lower 95% confidence bands. BMI, body mass index; FFMI, fat-free mass index.(TIF)Click here for additional data file.
