Multi-pollutant models for PM2.5, ambient NO, and room NO
| Pollutant | Estimated change in FeNO (ppb) for an interquartile change in pollutant measure* | |||
|---|---|---|---|---|
| Model 1 | Model 2 | Model 3 | Model 4 | |
| *Each model includes pollutant variables for which estimates are reported, as well as the following covariates: subject ID, week of study, day of week, hour of day, and 24 hour mean temperature, pressure, and relative humidity. Significant effects (p<0.05) are shown in bold. | ||||
| PM2.5 (24 hour) | ||||
| Effect | 1.95 | 1.38 | – | 1.97 |
| 95% CI | (0.47 to 3.43) | (0.26 to 2.51) | (0.48 to 3.46) | |
| p value | 0.011 | 0.017 | 0.011 | |
| Ambient NO (24 hour) | ||||
| Effect | 0.54 | – | 0.73 | 0.43 |
| 95% CI | (−0.10 to 1.18) | (0.12 to 1.34) | (−0.25 to 1.10) | |
| p value | 0.099 | 0.02 | 0.215 | |
| Indoor NO | ||||
| Effect | – | 0.69 | 0.26 | 0.30 |
