Demographics and the delivery details for all mothers.

*<p>Note that the estimated means and standard deviations for gestation at delivery and birth weight were corrected for fetal sex, maternal education (education was re-coded as an ordinal variable: 0 = 0 GCSEs; 1 = <5 GCSEs; 2 = >5 GCSEs/A-levels/degree), and maternal age as derived from the ANCOVA (IBM SPSS Statistics Version 20, NY, USA).</p

MR Images through the fetal brain in three orthogonal planes (HASTEbrain sequences), 24 weeks (V1) and 35 weeks (V2).

The mean and standard error for fetal organ volumes, placenta volume and total fetal volume at Visit 1.

<p>The mean and standard error were corrected for fetal sex, maternal education (education was re-coded as an ordinal variable: 0 = 0 GCSEs; 1 = <5 GCSEs; 2 = >5 GCSEs/A-levels/degree), gestational age at Visit 1 and the difference in gestational age between Visits 1 and 2.</p

Brain growth data showing group results at both visits and individual data.

The mean and standard error for fetal organ volumes, placenta volume and total fetal volume at Visit 2.

<p>The mean and standard error were corrected for fetal sex, maternal education (education was re-coded as an ordinal variable: 0 = 0 GCSEs; 1 = <5 GCSEs; 2 = >5 GCSEs/A-levels/degree), gestational age at Visit 1 and the difference in gestational age between Visits 1 and 2.</p

The effect of exposure on the volume of fetal organs was assessed using a mixed model ANCOVA.

<p>Each independent analysis included one within-subject variable of visit and one between-subject variable of exposure to maternal cigarette smoking, with four covariates.</p
