Univariable and multivariable comparisons of clinical and ultrasound risk factors for Normotensive-SGA by customised birthweight centiles.

Data are mean (SD) number (%) as appropriate, italics indicate variable is protective.*missing data numbers for woman’s birthweight (SGA n = 19, no SGA 178 missing.**missing data numbers for head circumference z score th centile (SGA n = 2, no SGA n = 23 missing).***missing data numbers for abdominal circumference z score th centile (SGA n = 1, no SGA n = 12 missing).†Unimputed data was used for univariate analyses.††Unimputed ultrasound data was added to the multivariable models derived from 15 week imputed data.NT SGA = birth of an SGA infant where the mother did not develop hypertension.Non NT SGA = all women in the remainder of the cohort who did not have Normotensive-SGA pregnancies.
