Outcome rates standardised for gestational age and CRIB score
| LL | LH | HH | p Value | |
|---|---|---|---|---|
| Values are % (95% confidence intervals). Predicted from a logistic regression model equation with gestational age set to 28 weeks and CRIB score set to 2.1, the approximate median values. | ||||
| CRIB, Clinical risk index for babies23; PMA, postmenstrual age; ROP, retinopathy of prematurity; LL, received low ascorbic acid (AA) supplementation throughout; LH, received low AA until day 10 and then high; HH, received high AA throughout. | ||||
