Extended Data Table 3 The spatial scale dependence of the relationship between crop diversity and stability. Specifically, we tested the interaction between crop diversity and land area, total harvested area or geographic crop land area

From: Larger nations benefit more than smaller nations from the stabilizing effects of crop diversity

  1. Note that we have ignored the main effect of area due to strong multicollinearity (VIF > 10). Sample size (n) is 673. The two-sided t-test was used for statistical significance testing.
