2. Consistency is the first criterion for establishing a causal relationship. This consistency must be between the supposed causal factor and its presumed effect. The condition in question must occur when the factor is present, not when it is absent. Frequency is not a criterion for establishing a causal relationship. Absolute risk is the probability that anyone in a given population will develop a particular condition. Susceptibility is the ability to be affected by factors contributing to a particular health condition.
