Circles and Xs represent values computed for individual matched pairs with dexamethasone and hydrocortisone treatment, respectively; shaded areas represent regression lines and 95% CIs. The regression line for death or neurodevelopmental impairment (NDI) is y = 0.131 – 0.221x for dexamethasone and y = 0.167 – 0.384x for hydrocortisone. For dexamethasone, the regression line crosses the x-axis at a pretreatment probability of death or grade 2 or 3 bronchopulmonary dysplasia (BPD) of 59% (95% CI, 48%-74%) for dexamethasone and 44% (95% CI, 21%-56%) for hydrocortisone. The regression line for death or cerebral palsy crosses the x-axis at 42% (95% CI, 31%-50%) for dexamethasone and 40% (95% CI, 28%-48%) for hydrocortisone. PMA indicates postmenstrual age.
