Table 1 Summary of statistical analysis plans
Objective | Statistical technique | Outcome variable | Main exposures | Covariates |
|---|---|---|---|---|
1 | Linear regression | concentrations of metabolic hormones in colostrum (e.g. adiponectin) | maternal metabolic characteristics (e.g., glucose intolerance, insulin resistance, obesity) | maternal lifestyle, SES, medical history |
2 | Linear regression | concentrations of metabolic hormones in mature breast milk at 3 months postpartum | concentrations of metabolic hormones in colostrum | maternal lifestyle, SES, medical history, maternal metabolic characteristics |
3 | Linear regression | metabolic characteristics in offspring (e.g. infant growth, adiposity) during the first year of life | concentrations of metabolic hormones in colostrum | maternal lifestyle, SES, medical history, maternal metabolic characteristics, infant feeding/supplementation behaviors |
4 | Logistic regression | delayed onset of lactogenesis II | maternal metabolic characteristics (e.g., glucose intolerance, insulin resistance, obesity) | maternal lifestyle, SES, medical history |
