Groups 2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code | Source |
|---|---|---|---|---|---|---|
| Group 1 | No PN Use (Project B) | All neonates born between 30 and 33 weeks postmenstrual age in England and Wales and admitted to a NHS neonatal unit between 1st January 2012 and 31st December 2017 who did not receive any parenteral nutrition (for any duration, by any intravenous route) in the first seven postnatal days. | 69 | 8,146 | OG000 | ClinicalTrials.gov |
| Group 2 | PN Use (Project B) | All neonates born between 30 and 33 weeks postmenstrual age in England and Wales and admitted to a NHS neonatal unit between 1st January 2012 and 31st December 2017 who received any parenteral nutrition (for any duration, by any intravenous route) in the first seven postnatal days.~Parenteral nutrition: Parenteral nutrition is the administration of an intravenous solution containing amino acids (with or without lipids) to provide nutritional support. | 147 | 8,146 | OG001 | ClinicalTrials.gov |
