Primary outcome and related outcomes*
*Data presented as number (%).
†Criterion 1: at least 2 of the following:
a) an increase in the greatest occipital-frontal circumference adjusted for gestational age defined as crossing percentiles (if a plateau was reached this did not qualify);
b) bulging fontanelle or split sutures or sunsetting sign;
c) increasing hydrocephalus on consecutive imaging studies determined by increase in ratio of biventricular diameter to biparietal diameter according to the method of O’Hayon et al.; or
d) head circumference > 95th percentile for gestational age.
Criterion 2: presence of marked syringomyelia with ventriculomegaly.
Criterion 3: ventriculomegaly with symptoms of Chiari malformation (stridor, swallowing difficulties, apnea, bradycardia).
Criterion 4: persistent CSF leakage from the myelomeningocele wound or bulging at the repair site.

‡Of those who had shunts placed.
Subgroup analyses for shunt placement and outcome with revised criteria
*Revised composite outcome is defined as follows:
Shunt placement or death or meeting revised criteria as follows:
Criterion 1: bulging fontanelle or split sutures or sunsetting sign with at least 1 of the following:
a) increase in the greatest occipital-frontal circumference adjusted for gestational age defined as crossing percentiles (if a plateau was reached this did not qualify);
†p value for interaction between factor and surgery group by logistic regression adjusting for sex and lesion level.
‡Ventricle size and gestational age are included as continuous variables in the model.
