Why the study?
CVD is the leading cause of death in Costa Rica and sodium intake is twice the WHO recommendation, prompting estimation of the impact of reducing salt intake on CVD mortality.
Does salt intake reduction prevent or delay CVD mortality in the Costa Rican population?

Supports existing salt-reduction policies but should not change practice; leaves open real-world effect given modeling limits.
Does salt intake reduction prevent or delay CVD mortality in the Costa Rican population?
Scenario modelling suggests that reducing salt intake by 15-46% in Costa Rica could prevent or postpone 4-13% of cardiovascular deaths.
