  1. The table shows the mean difference [95% CI] (kg) in fat mass for offspring of externally compared with internally oriented women
  2. Model A allows for sex and ethnicity of the child; model B additionally allows for duration of breast feeding, age started solids and whether the mother smoked at mid-pregnancy; model C is model B plus aspects of the offspring diet at ages 10 (energy, trans-fatty acids and sugar) and activity levels at 11
  3. MD mean difference, CI confidence interval
