Variables significantly associated with Bayley-III motor score in ‘before’ cohort
| p Value | R Square | Estimate variation of motor score (SD) per Δ of unit of measurement* | |
|---|---|---|---|
| Growth velocity in the first 30 days after regaining birth weight (10 g/kg/day) | 0.04 | 0.12 | 8.4 (4.0) |
| Week 1 enteral protein (g/kg/day) | <0.0001 | 0.41 | 16.6 (3.7) |
| Enteral protein intake first 2 weeks (g/kg/day) | 0.003 | 0.22 | 8.1 (2.6) |
| Enteral protein first 30 days (g/kg/day) | 0.02 | 0.15 | 6.8 (2.7) |
| Total energy intake first 30 days (10 kcal/kg/day) | 0.03 | 0.12 | 3.3 (1.5) |
| Week 1 enteral volume (10 mL/kg/day) | <0.001 | 0.30 | 2.4 (0.9) |
| Full enteral feeds and no intravenous nutrition given (per day of life) | <0.001 | 0.17 | −1.0±0.3 |
*To make the estimate variation more comprehensible to the reader we ran a univariate analysis with raw data rather than normalised data.
