RSV Respiratory syncytial virus, OR Odds ratio, LCL 95% lower confidence limit, UCL 95% upper confidence limit, Ref Reference value
¹Mean minimum (low) daily temperature during 7–13 days period prior to RSV hospitalization (representing time during likely RSV exposure and infection)
²AQHI = Air quality health index and ranges from 0 to 10+, higher value indicates worse air quality
³O3 = ground level ozone concentration in parts per billion
⁴p < 0.05 indicates statistically significant associations
