a

Risk group defined as babies with one or more of: previous toxaemia (multiparae only); previous baby <2500 g (multiparae only); maternal psychiatric disorders (primiparae only); contracted pelvis or short stature (primiparae only); intrauterine growth restriction (IUGR) in current pregnancy; imminent preterm delivery in current pregnancy; toxaemia in current pregnancy (primiparae only); hydramnios in current pregnancy; not having attended antenatal care in current pregnancy (assessed at term; multiparae only); breech, footling presentation or transverse lie in current pregnancy

b

Presumed infection defined as administration of antibiotics, even if the diagnosis was not confirmed by microbiological culture
