Two sets of analyses were carried out to test for the effects of the dietary treatment on the psychoeducational and information-processing tests administered in 1988 and on the subjects' educational record. The first included all subjects for whom schooling data were available and assessed whether the nutritional treatment was associated with test performance. The second was restricted to subjects who never enrolled in school.
