PRIMARY outcome

Timeframe: at time of birth

Population: The effect of DHA supplementation on study primary outcomes was determined for black and non-black subjects separately. Researchers did not compare outcomes between black and non-black subjects to determine whether they were statistically different. For measures reporting black and non-black results, there were 184 non-black and 117 black subjects.
