From: Acute association between heatwaves and stillbirth in six US states
Odds ratios and 95% confidence intervals for the association between heatwaves and stillbirth in California, Florida, Georgia, Kansas, New Jersey, and Oregon. The reference category for heatwave definition 1 (dark blue lines, circles) is 0 hot days in the previous week. Heatwave definition 2 (blue lines, squares) are dichotomous exposure categories. Heatwave definition 3 (green line, triangle) presents the odds ratio associated with a 1° increase in the average degrees over the 97.5.th percentile in the previous week. All models adjusted for maternal age, LMP month, and LMP year; cases matched 1:4 to controls based on maternal race/ethnicity, education, and county. Estimates shown in Supplemental Table 2
