If temporal ambiguity is not addressed, it can lead to several issues:
1. Misleading Associations: Incorrect conclusions about the relationship between exposure and outcome can be drawn. 2. Ineffective Interventions: Public health policies based on faulty causal inferences may be ineffective or even harmful. 3. Confounded Results: Temporal ambiguity can introduce confounding, where the observed effect is actually due to an unmeasured variable.
