| 750–1499 g (n = 94, 103) | 26 (27.7) | 22 (21.4) | |
| Antenatal corticosteroids received | 0.24 | ||
| No (n = 11, 3) | 6 (54.6) | 3 (100.0) | |

P values are from tests of heterogeneity of the treatment effect on the relative risk scale, estimated using log binomial regression models fit using generalized estimating equations. The number (N) of infants within each subgroup are noted in parentheses in the first column. Incidence data for subgroup comparisons are shown as N (%).
