Maternal characteristics	One-child policy period	Partial two-child policy period	Universal two-child policy period
Number (%)
Maternal near miss	75 (27.7)	45 (16.30)	156 (56.52)
Stillbirth	105 (42.00)	60 (24.00)	85 (34.00)
Weighted rate, per 100 births^a
Maternal near miss	5.46	1.72	1.99
Stillbirth	8.18	2.02	1.04
Crude odds ratio^a
Maternal near miss	1	0.32 (0.19–0.52)	0.36 (0.21–0.65)
Stillbirth	1	0.25 (0.16–0.38)	0.13 (0.08–0.20)
Adjusted odds ratio^a,b
Maternal near miss	1	0.60 (0.32–1.17)	0.90 (0.52–1.53)
Stillbirth	1	0.57 (0.37–0.83)	0.36 (0.24–0.54)

^aWeighted for the sampling distribution of the population covered by the Chinese National Maternal Near Miss Surveillance System
^bAdjusted for the clustering of births within hospitals; region; hospital level; maternal sociodemographic characteristics (maternal age, parity, previous caesarean sections, education level, marital status, and number of antenatal care visits); and maternal obstetric characteristics (foetal presentation, delivery methods, foetal sex, and foetal weight)
