| AF in the exposed, % ((HR−1)/HR) | Men | Women |
| Ever exposed cumulative exposure (mg/m3) | 1.4 (0.7–2.2) | 15.4 (9.4–21.0) |
| Q1 0–0.27 | −2.1 (−7.0–2.6) | 15.1 (−7.0–32.5) |
| Q2 0.27–0.62 | −3.6 (−8.2–0.9) | 6.9 (−19.5–27.5) |

| Q4 1.54+ | 6.1 (2.8–9.2) | 39.8 (21.1–54.1) |
| Population attributable fraction % p* ((HR−1)/HR) | Men | Women |
| Ever exposed | 0.4 (0.2–0.6) | 0.4 (0.2–0.5) |
| Cumulative exposure (mg/m3) | ||
