Use of natural experiments to evaluate public health policy
(3 days ago) WEBA key task of public health research is investigation of the causal effect of policies aimed at improving health outcomes. However, such a task is often challenging because a study in which a population is randomised into exposed and unexposed groups is generally not feasible owing to practical and ethical constraints. In certain settings, a so-called natural …
