Linear regression results for correlation of left and right EAC obstruction (considering left EAC obstruction as a dependent variable)

Dependent variable	r	B	r 2	p-value	Formula
Left EAC obstruction	0.42	0.45	0.17	0.02*	1.84 + 0.45 (right EAC obstruction degree)

*significant correlation between left and right EAC obstruction. Abbreviations: r – Pearson’s correlation coefficient; B – Model coefficient; r² – square of Pearson’s correlation coefficient; formula predicts the left EAC obstruction based on the degree of right EAC obstruction.
