| Spearman’s correlation (rs) | P | Spearman’s correlation (rs) | P | |
| Gestational age | −0.26 | < 0.001 | − 0.30 | < 0.001 |
| Number of painful procedures | 0.07 | 0.24 | 0.03 | 0.61 |
| Number of sucrose doses since birth | 0.004 | 0.95 | −0.02 | 0.74 |
PIPP-R scores range from 0 to 21. Higher scores indicate greater pain intensity. SNAPPE-II scores range from 0 to 158. Higher scores indicate greater severity of illness
