Logistic regression to evaluate the effect of different perinatal factors on NDI

OR (95% CI)
GA (days)0.98 (0.93 to 1.03)
Female0.95 (0.53 to 1.79)
SGA1.47 (0.66 to 3.07)
NEC1.32 (0.51 to 3.02)
Severe brain injury2.63 (1.32 to 5.05)*
Low maternal education2.58 (1.26 to 5.03)*
  • Numbers are presented as OR with 95% CI. Being female was compared with the reference category of being male, low maternal education was compared with a reference category of intermediate–high education. *significant at 0.05 level.

  • GA, gestational age; NDI, neurodevelopmental impairment; NEC, necrotising enterocolitis ; SGA, small for gestational age.
