Summary of significant (and marginally significant*) p-values and adjusted R² values emerging from three stepwise backward elimination regressions that revealed relationships between CI, height, bodyweight and owner reports of 33 behavioral traits of companion dogs (n = 8,301) of various common breeds (n = 49).

a<p>Regression coefficients with CI were positive, apart from those with chasing, stranger-directed fear, persistent barking, and stealing food.</p>b<p>All regression coefficients with height were negative, apart from the correlations of height with trainability.</p>c<p>All regression coefficients with weight were negative, apart from the correlations of weight with other stereotypic behaviors, emotional urination, tail-chasing/spinning, snapping at flies, stranger-directed aggression and being nervous on stairs.</p><p>Empty cells denote the absence of any significant regression coefficients. The <i>adjusted</i> R² value is a more reliable estimate of the amount of variation explained by an explanatory regression model.
