The relationship between DACT1 expression and connexin 43 (Cx43) expression in the myocardium of patients with valvular heart disease.

Cx43 expressionb	DACT1 expressiona		P Spearman's rho

^aAs long as the sample contained cells with the dishevelled binding antagonist of beta catenin 1 (DACT1) cytoplasmic staining, the staining was regarded as weak if mean density was <0.025, strong if it was between ≥0.025 and <0.04, and very strong if it was ≥0.04;

^bAs long as the sample contained cells with connexin 43 cytoplasmic and/or membrane staining, the total expression level was regarded as negative if mean density was <0.01, very weak if it was between ≥0.01 and <0.03, weak if it was between ≥0.03 and <0.04, strong if it was between ≥0.04 and <0.05, and very strong if it was between ≥0.05. The nonparametric Spearman's rank correlation test was used for correlation analysis.

^*P<0.05.
