2. Figure 1
Risk of stillbirth according to parental country of origin, further modified by the exposure status. The main model (top) uses Canadian-Canadian parents as the reference group, and compares them with the two cases of one Canadian-born and one immigrant parent, as well as with immigrant parents from either the same or different countries of origin. Below the main model is the same data under six separate restrictions.
*Adjusted for infant sex, maternal age (<20, 20–34, ≥ 35 years, unknown), parity (0, 1, 2, 3, ≥4, unknown), marital status (married/common-law, unmarried, unknown), and residential income quintile (Q1–Q5, unknown).
†Comprises all structural congenital and chromosomal anomalies
‡Restricted to all stillbirths and live births

Risk of stillbirth for couples from the same country. Post hoc analysis restricted to foreign-born parents from the same country, compared to parents who are both Canadian-born. Data are presented for the top 20 immigrant countries that contribute to same-country births in Ontario.

4. Figure 3
Risk of stillbirth according to parental country of origin, compared to couples who are both Canadian-born, and stratified by low or high stillbirth rate in maternal and paternal country of origin. A country was classified as having a high stillbirth rate if that rate was≥80th percentile for all nations.17
