The analyses represent multivariable linear regression models showing the regression coefficients (β) and the 95% confidence interval (CI) for the relationship (Equation 1) of aBW (grams) to the corrected maternal weight in kg (see Methods) and natural logarithm of the maternal serum leptin concentration (ln [ng/mL]). The values in this table represent the conditional effect of variation in the rate (either ln [kg]/week or ln [ng/mL]/week) of the predictors across visit intervals (the coefficients for X02 and X24 in equation 1) on variation in aBW in the context of variation on the magnitude of the predictor at ANY visit (the coefficient for X0). Results were adjusted for the following maternal covariates: race, parity, education, income.
