Developmental delay

1. Developmental delay decreases abdominal aortic diameter in humans (-1.16±0.046 mm (95% CI: -1.07 to -1.25 mm)).

   “the average difference in abdominal aortic diameter in this group was -1.16±0.046mm (95% CI: -1.07 to -1.25 mm)”

1. Developmental delay is associated with descending aortic diameter Z-score in humans (standardized coefficient -0.35 (SE 0.045, p=4.81x10^-14)).
