Risk predictor (risk marker)
	n Risk predictor (risk marker) – A characteristic associated with elevated risk of disease (i.e., it predicts well) – Not thought to be part of the causal chain (e.g., tooth loss is a good predictor of future disease) – Usually either a byproduct of the causal chain (usually called a risk marker) – Or some historical measure of the outcome, such as number of missing teeth, or baseline caries – Useful to identify who is at risk, but not useful in identifying likely interventions
