Table 1_From evidence to implementation: a stakeholder power–interest and social network analysis of potassium-enriched low-sodium salt governance in China.docx

Government agencies constituted the largest group (36, 43.4%), followed by professional associations (20, 24.1%) and academic institutions (14, 16.9%). Eight stakeholders (9.6%) were classified as Key Players, 21 (25.3%) as Supporters, 27 (32.5%) as Potential Allies, and 27 (32.5%) as Monitored Stakeholders. Key Players were concentrated among a small number of government, public-health, industry, professional, and media actors, whereas many high-power government bodies had limited documented potassium-enriched low-sodium salt-specific engagement.

The four relationship-specific networks contained 25–57 participating stakeholders and had low densities of 0.03–0.10. Policy/regulatory relationships were centered on national and provincial health authorities, while advocacy and technical advisory ties were concentrated around the collective categories of the public and healthcare providers, respectively.</p>Conclusion<p>The documented stakeholder landscape was characterized by uneven alignment of power, interest, and institutional connectivity.

These patterns present governance challenges for evidence translation but do not establish the causes of limited scale-up. Stronger engagement among high-power actors and clearer coordination across regulatory, technical, industry, and implementation networks are needed to support wider implementation of potassium-enriched low-sodium salt.</p>
