Educational only. Associations do not establish individual risk or diagnosis. Read the original sources and limitations.
Context
The salt-substitute trial provides a specific intervention example from rural China, rather than a claim about an entire regional diet.
Applicability
Local study: 600 Chinese villages with older or higher-risk participants. PURE also included China.
Evidence gaps
Results do not automatically apply to all ages, urban populations, or every East Asian country. Salt substitution changed potassium as well as sodium.
Scope
An editorial research lens, not a regional mortality ranking or an estimate of individual risk.
