Fig. 3From: Acute associations between heatwaves and preterm and early-term birth in 50 US metropolitan areas: a matched case-control studyOdds ratio estimates for heatwave indicators: HW1 (top horizontal strip), HW2 (middle strip), and HW3 (bottom strip) for 97.5th percentile for temperature metrics (left column) and 85th percentile of positive EHF for EHF metric (right columns) for early-term (panel A) and preterm birth (panel B). Temperature metrics were grouped based on apparent temperature (AT, square) and temperature (T, solid circle) and minimum (orange), mean (blue), and maximum (black) temperatureBack to article page
