Risk Factors
An environmental, behavioral, or biologic factor
confirmed by temporal sequence, usually in
longitudinal studies, which if present directly
increase the probability of a disease occurring, and
if absent or removed reduces the probability. Risk
factors are part of the causal chain, or expose the
host to the causal chain. Once disease occurs,
removal of a risk factor may not result in a cure.
