Odds (95% CI) are for trend, calculated by logistic regression models with the year of birth as a continuous variable, and adjusted for gestational age at birth1, sex2, centre3 and outborn-status4, along with the interaction terms gestation*year of birth5, gestation*gender (1)6 and centre of care*outborn-status (1)7.
$All analysis was conducted after excluding missing data.
!Superscript numbers indicate significant independent variable on adjusted analysis as numbered above.
