Theoretical example of multicausality and how it affects PAFs for single causal factors
| Causal mechanism | |||
| 1 | 2 | 3 | |
| Risk factors causally involved | A, D, E | A, B, C | B, D, E |
| PAF for each causal mechanism | 40% | 35% | 25% |
| PAF for causal factor A | 40%+35%=75% | NA | |
| PAF for causal factor B | NA | 35%+25%=60% | |
NA: not applicable.
