Time-to-event analysis of birth before 37 weeks by adherence with 1000 mg assigned dose using planned definition of adherence (red blood cell phospholipid or RBC-PL-DHA ≥5.5%). The number of births at each gestational age is cumulative. At 34, 35, 36 and 37 weeks, Bayesian posterior probabilities (pp) that the adherent group (1000+ mg) was superior to the 200 mg group were pp=0.93, 0.95, 0.98 and 0.99, respectively. The adherent group was also superior to the nonadherent group (1000- mg), respectively, 0.85, 0.92, 0.99 and 0.99, for these weeks. The non-adherent group (1000- mg) had a higher rate of PTB than the 200 mg group at 37 weeks gestation (pp=0.97) but was similar at 34-, 35- and 36-weeks’ gestation.
