What might link these
Greater egg production may reflect agricultural capacity or dietary habits, which could correlate with trade activity. However, population and GDP controls reduced the strength, suggesting these factors partially explain the link. A likely confounder is economic development, which influences both trade and agricultural output.
Why this is not proof of anything
This is a correlation across countries, not an experiment. It cannot show that either indicator causes the other, and both may simply follow a third thing. Correlation does not imply causation; other unmeasured factors may drive this relationship.
The second figure above repeats the measurement with national population and income held constant. It is the more conservative number: a relationship that largely disappears there was mostly telling you that larger, richer countries have more of most things.
How this was measured
Both indicators were ranked across every country reporting each, and the two rankings compared — ranks rather than raw values, because a handful of very large countries can otherwise manufacture a relationship on their own. The calculation is arithmetic over figures already published on this site; the commentary above is drafted from the two indicator names and the resulting coefficients.
