Table 2. Associations between long-term PM2.5 and cause-specific mortality.
| Mortality types | Brisbane | Queensland | ||
|---|---|---|---|---|
| Percent increase (95% CI) | p-Value | Percent increase (95% CI) | p-Value | |
| Non-accidental | 5.65 (4.08–7.25) | <0.01 | 1.92 (1.36–2.63) | <0.01 |
| Cardiovascular | 4.08 (2.02–6.18) | <0.01 | 1.41 (0.60–2.22) | <0.01 |
| Respiratory | 7.25 (3.05–11.29) | <0.01 | 5.44 (3.67–7.25) | <0.01 |
| Total | 5.65 (4.08–7.25) | <0.01 | 2.02 (1.41–2.63) | <0.01 |
Total mortality includes 7 kinds of classification of diseases (ICD-10: F00–F99, G00–G99, I00–I99, J00–J99, K00–K93, N00–N99, V01–Y98). Non-accidental causes include all the above diseases except for V01–Y98. Cardiovascular deaths (ICD-9: 390–459; ICD-10: I00–I99); respiratory causes (ICD-9: 460–519; ICD-10: J00–J99).
Abbreviation: PM2.5, fine particulate matter (particulate matter with a diameter of <2.5 μm)
