  1. AHI, apnea hypopnea index; SE, standard error; Model 1, bivariate linear regression with birthweight percentile as the dependent variable; Model 2. multivariate linear regression with birthweight percentile as the dependent variable and AHI as the independent variable, adjusted for parity and pre-pregnancy body mass index.
