The distribution of DQ18 scores was categorised into four levels of development: <70, significant developmental delay; 70–84, moderate developmental delay; 85–99, without developmental delay; ≥100, average development or better.Results Among 153 infants assigned to the OLB6378 administration group and 130 assigned to the placebo administration group, 102 and 105 infants, respectively, underwent the 18-month medical examination. The distribution of developmental levels (DQ18 scores <70, 70–84, 85–99 and ≥100) was significantly more favourable for OLB6378 administration (12, 12, 25 and 40 infants, respectively) than for placebo administration (15, 17, 23 and 24 infants, respectively) (ordered logistic regression analysis: partial correlation coefficient, 0.589; P value, 0.038).Conclusions Although limited by assessment rates, result suggests that OLB6378 may have a beneficial effect on the psychological development in VLBW infants.Clinical trial registration UMIN000002543.
