Every euro invested in health prevention can generate up to 14 euros in return through lower costs and higher productivity.

• The 14:1 figure originates from a 2017 systematic review (Masters et al.) covering multiple high-income countries, not from an EU-specific dataset; it is an average/median, not a guaranteed ceiling, and no EU statistical office publishes this ratio.
• The same body of evidence indicates that nationwide prevention programmes can yield a median return of about 27:1, so the 'up to 14 euros' framing actually understates the upper potential rather than overstating it.
• The sources found are think-tank, industry-association and NGO analyses (Centre for European Reform, Friends of Europe, IFPMA, Pew) rather than a primary official (Eurostat/Commission) publication, so the exact magnitude is corroborated by secondary sources only.
