*Paediatric analysis is based on 9:1 nearest-neighbour matching with deduplication based on age and gender.
†Adult analysis is based on 6:1 nearest-neighbour matching with deduplication based on age and gender.
‡Data are reported as n (%) unless otherwise noted.
§Attributable fraction is reported as a percentage and is only given for the dichotomous delays significantly associated with mortality on conditional logistic regression analysis.
¶We also estimated the OR for this delay at the first facility, the last facility and the first or last facility, none of which were significant.
**Data reported as mean (SD).
AF, attributable fraction.
