Table 4.
Final multivariable model results showing the associations between weekly average ambient exposures and increased proportions of lower airway granulocytes (n = 78, 2007–2017).
| Exposure | Odds Ratio | 95% CI | p-value |
|---|---|---|---|
| Mean ambient temperature (°C) | |||
| 1-week lagged | 1.13 | 1.02–1.26 | 0.02 |
| Mean NO2 | |||
| 3-week lagged | 1.24 | 1.08–1.43 | 0.03 |
| Mean PM2.5 | |||
| 2-week lagged | 1.11 | 1.01–1.22 | 0.04 |
Statistically significant associations (p <0.05) are in bold-face type. Mean values for ambient temperature, nitrogen dioxide (NO2), fine particulate matter <2.5 microns diameter (PM2.5). Odds ratio, 95% confidence interval (CI), and p-value of the estimate.
