In observational studies, controlling for potential confounders is crucial to establish a stronger empirical association between variables. Confounders are variables that can affect both the independent and dependent variables, potentially misleading the association between them. Identifying and adjusting for these confounders helps in isolating the effect of the independent variables on the dependent variable, thereby strengthening the empirical association observed.
