• The numeric value is the whole-study breed-effect chi2 for this trait, not a Russian Blue-specific score -- read the subject text, not the number, for the named breeds.

Method

Named highest/lowest breed from the paper's own Results text; value is that trait's Table 1 breed-effect chi2, not a per-breed score (the paper does not publish per-breed probabilities as text/table data -- see data/temperament-salonen2019.json's notes).

n = 5726
