Characteristics of the cohort
Table 1 describes the study cohort of 1,572,817 births, of which 6,569
were stillborn (rate 4.18/1000).
Of the 1,308,967 cases where the results of early pregnancy risk
assessment were recorded, 990,199 were designated low risk and had a
stillbirth rate (per thousand) of 3.61 (Table 2). Cases where risk
status was not recorded had a similar stillbirth rate (3.82, P=0.11).
