Poisson regression analyses of death from mesothelioma in relation to various indices of exposure
| Exposure index | Deaths observed | Adjusted relative risk (95% CI) | p value | |
|---|---|---|---|---|
| All analyses exclude deaths and person-years in the first 10 years of follow up. Analyses by intensity category also exclude subjects not completing five years of employment. | ||||
| Intensity category (mean) | ||||
| 1: | 0- (1.5) | 1 | 1.00 | |
| 2: | 2.38- (3.9) | 4 | 3.36 (0.37 to 30.87) | |
| 3: | 6.45- (11.5) | 2 | 2.32 (0.21 to 26.12) | |
| 4: | 26.17- (60.4) | 2 | 2.14 (0.19 to 23.89) | |
| Linear model (per 10 f/ml.y) | 0.02 (<0 to 1.08) | >0.20 | ||
| Cumulative exposure | ||||
| 1: | 0- (8.6) | 1 | 1.00 | |
| 2: | 11.7- (16.7) | 4 | 3.72 (0.41 to 33.46) | |
| 3: | 25.2- (53.2) | 3 | 3.42 (0.35 to 33.15) | |
| 4: | 113.8- (393.8) | 4 | 3.68 (0.41 to 33.22) | |
| Linear model (per 100 f/ml.y) | 0.10 (<0 to 1.81) | >0.20 | ||
| Residence weighted exposure | ||||
| 1: | 0- (144) | 0 | (combined with 2) | |
| 2: | 235.4- (349) | 3 | 1.00 | |
| 3: | 500.1- (943) | 4 | 1.57 (0.35 to 7.07) | |
| 4: | 1826.9- (6976) | 5 | 1.95 (0.45 to 8.51) | |
| Linear model (per 1000 f/ml.y) | 0.03 (<0 to 0.64) | >0.20 | ||
