Maternal Oral Therapy to Reduce Obstetric Risk Kids

A total of 525 infants where planned to be enrolled at the 3 performance sites. The number of
infants enrolled at each site depended on past Motor recruitment rates, and the observed
delivery rate of high risk babies at that site. Infants were enrolled from both the high risk
and low risk groups. The intended sample size was fixed, over sampling among the low risk
group and was used to assure the sample size.

The Data Coordinating Center (DCC) identified and provided each clinical site with
participant listings of all MOTOR high risk births and a randomly ordered sample of low risk
births for enrollment into the study.

Mothers where approached by MOTOR or MOTORkids personnel to ascertain participant interest in
enrolling their infant. Once consent was obtained, infants were followed and tracked until
scheduled for the follow-up exams at age 24 months +/- 2 months adjusted age.

Inclusion Criteria:

- All infants born to mothers enrolled to MOTOR study prior to 35 weeks gestational age,

- All small for gestational age (SGA) infants and all infants born after 37 weeks
gestation and who were appropriate for gestational age are eligible for enrollment.

- All infants born < 34 weeks gestation and all SGA infants will be considered a high
risk infant and will be recruited for enrollment.

- Appropriate weight for gestational age infants born after 37 weeks will be considered
low risk infants and a random sample of these infants will be recruited for
enrollment.

Exclusion Criteria:

- Only a random sample of the low risk group will be recruited.
