Table 2 Simple linear regression showing associations between 25OHD (independent variable) and offspring anthropometrics (dependent variables)

From: An examination of whether associations exist between maternal and neonatal 25OHD and infant size and adiposity at birth, 6–9 months and 2–2.5 years of age – a longitudinal observational study from the ROLO study
