SGA <10^th percentile: Risks and relative risks of delivery and expectant management

Gestational week	Composite risk of expectant management × 2 weeks/10,000^* (95% CI)	Risk of neonatal death/ 10,000 (95% CI)	RR of expectant management 2 weeks compared to delivery (95% CI)
24-25^6/7	2,534 (2,449-2,620)	4,444 (4,346-4,542)	0.63(0.61-0.66)
26-27^6/7	1,020 (961-1,081)	2,500 (2,415-2,586)	0.53 (0.50-0.56)
28-29^6/7	199 (173-228)	1,000 (942-1,060)	0.32 (0.28-0.36)
30-31^6/7	109 (90-131)	192 (166-221)	0.72 (0.62-0.84)

Composite risk= risk of stillbirth at this gestational age + risk of infant death in the next strata
