Odds Ratio (OR, corrected for SMME where applicable) and 95% Confidence
Interval (CI) of Recent Wheeze for an Interquartile Range Increase in
Residential NOx Exposure as Estimated by the Different Stages (1–3) of
the Li et al. (2017) [41] Spatiotemporal
Model. Mixed-effect models were used to determine ORs and 95% CI for recent
wheeze using exposure predictions from the individual 120 ensembles (yellow).
The mean OR was calculated (red) to represent the average health effect estimate
of stage 1 of the spatiotemporal model. Health models using stage 2 (green) and
stage 3 (purple) NOx estimates were included for comparison. Health effect
estimates from stage 2 corrected for SMME are shown in blue. All models were
adjusted for maternal race, premature birth, child sex, baseline community,
child age, child body mass index, maternal education, crowding in home, maternal
and paternal allergy history.
