πC·πX |
C and X are independent |
| 2 |
πC|X·πX |
C and X interact and πC|X or πX|C is known. |
| 3 |
πX|C·πC |
|
| 4 |
πC·πX / [πC + (1 - πC) / RRX|C] |
C and X are dependent and the relative risk RRX|C or RRC|X is known. |
| 5 |
πX·πC / [πX + (1 - πX) / RRC|X] |
X (C) either potentiates, or protects from, C (X). |
