description: Additional file 1: Figure S1. Map of Los Angeles-Long Beach-Santa Ana MSA. The MSA was split into Los Angeles county (mint green) and Orange county (light orange). Figure S2. Map of New York-North New Jersey-Long Island MSA. The MSA was split into the Long Island area (blue), New York City area (pink), and other New York and New Jersey counties (green). Figure S3. Illustration of the selection of pregnancies whose at-risk windows overlap with the warm season for preterm (blue) and early-term birth (orange) where pregnancy 1-4 (four arrow lines) are extreme examples determining the range of the eligible LMP dates. The at-risk window was defined as 28 weeks and 0 days to 36 weeks and 6 days for preterm birth and 37 weeks and 0 days to 38 weeks and 6 days for early-term birth. Figure S4. Flow chart of identification of preterm and early-term cases and matching control. Table S1.

Figure S5. Odds ratio estimates of heatwave indicators on early-term birth by maternal education (&lt;12 years, 12 years, and ≥13 years) using mean temperature over 97.5th percentile to quantify heatwave. P-values were calculated from the joint test for interaction. Figure S6. Odds ratio estimates of heatwave indicators on preterm birth by maternal education (&lt;12 years, 12 years, and ≥13 years) using mean temperature over 97.5th percentile to quantify heatwave.
