Which of the following is not a criteria suggesting casuality in non communicable diseases?
Strength of association
Dose response relationship
Specificity of association
Lack of temporal association
The presence of temporal association is included among the criteria designed by Sir Austin Bradford Hill in order to suggest causality in non-communicable diseases. Thus this criteria can distinguish between casual and non casual associations. Temporal association is based on the fact that the suspected cause should precede the observed effect.
