Relative risk estimates for atmospheric parameters from Poisson model to estimate daily event counts of different AVCDs (AMI: n = 5,221; thromboembolism: n = 1,211; AAR, AD: n = 28; PE: n = 63).
| Parameter* | Relative Risk | p-value for comparing estimates | |||
|---|---|---|---|---|---|
| AMI | thrombo-embolism | AAR, AD | PE | ||
| Daily atmospheric temperature change ≥5 °C | 1.190 | 1.011 | 0.775 | 1.451 | 0.253 |
| Daily atmospheric air pressure change ≥10 hPa | 0.909 | 1.29 | 1.038 | 0.600 | 0.979 |
| Daily humidity change ≥40% | 0.845 | 0.621 | 0.001 | 1.109 | 0.433 |
| Average daily atmospheric temperature, °C | 0.989 | 0.996 | 0.974 | 1.011 | 0.680 |
| Average daily atmospheric pressure, hPa | 1.002 | 0.998 | 0.999 | 0.997 | 0.360 |
| Average daily humidity, % | 0.999 | 0.998 | 0.996 | 1.01 | 0.192 |
| Average daily wind velocity over 2 m/s | 1.018 | 1.167 | 0.677 | 3.486 | 0.183 |
| Interaction of daily atmospheric temperature change ≥5 °C and humidity change ≥40% | 1.224 | 1.678 | NA | 0.974 | 0.433 |
| Interaction of daily atmospheric temperature change ≥5 °C and wind velocity ≥2 m/s | 0.989 | 0.894 | 2.006 | 0.323 | 0.070 |
*Parameters are adjusted for seasonality. Bold values indicate parameters significantly associated with daily event counts (p ≤ 0.05). NA indicates that reliable parameter estimation failed due to small sample size.
