| Dobryansky 2012 | 20 VLBW infants were randomised to both hydrocortisone and caffeine as active treatments, compared with "standard guidelines", which presumably meant no hydrocortisone or caffeine. Major reported outcomes included BPD and BPD combined with mortality. As caffeine reduces BPD (Schmidt 2006), the independent effect of hydrocortisone cannot be determined |
