Effects of the distribution of subjects per job on the performance of population specific JEM (resampling (two series of 100 draws) performed in men from the French survey)
| First series | Second series | |
| Men (mean (SD)) | 849 (6.4) | 3171 (4.1) |
| Different jobs (mean (SD)) | 110 (5.0) | 184 (3.6) |
| Self reported exposure (mean (SD)) (%) | 25.5 (1.5) | 25.8 (0.5) |
| Men in each category of job (mean (SD)) (%): | ||
| <10 | 40.2 (2.6) | 14.4 (0.8) |
| 10–19 | 17.9 (3.2) | 19.1 (1.4) |
| 20–49 | 25.9 (5.2) | 20.4 (1.8) |
| ⩾50 | 16.0 (4.4) | 46.0 (1.5) |
| Significant positive associations (between exposure and FEV1) out of 100 draws (n): | ||
| Self reported exposure | 6 | 8 |
| Pp JEM | 16 | 61 |
