This randomized clinical trial evaluated the effectiveness of low-dose aspirin alone or in combination with omega-3 supplements in treating asymmetrical intrauterine growth restriction (IUGR). 80 pregnant women between 28-30 weeks gestation with IUGR were randomly assigned to receive either aspirin alone or aspirin plus omega-3 for 6 weeks. The combination treatment was found to more significantly increase estimated fetal weight, uterine and umbilical blood flow, and birth weight compared to aspirin alone. The study concluded that while both treatments were effective for IUGR, the combination of aspirin and omega-3 was superior in improving fetal and birth outcomes.
