What this covers
Place: 143 countries (levels test); 116 countries (cut episodes)
Time covered: Tariffs 1990–2022; growth 1990–2025; descriptive checks
What this does not prove
Growth runs to 2025. Most of the 143 comparisons use three later years; three use two. Other policies, crises and changes in imports can affect both series. No clear link is not proof of no effect.
