Table 4. The relationship of DACT2 expression with fibrosis degree in myocardium of patients with valvular heart disease.

Fibrosis degree^b	DACT2 expression^a		P (Spearman rho)
Fibrosis degree^b	Weak	Strong	P (Spearman rho)
Weak	1	9	0.010*
Strong	9	8	−0.476
Very strong	1	0

^a, as long as the sample contained cells with DACT2 staining, the expression level was regarded as weak if mean density <0.004, strong if mean density ≥0.004; ^b, the level of fibrosis was regarded as weak if mean ratio <0.1, strong if mean ratio ≥0.1 and <0.3, very strong if mean ratio ≥0.3. Correlations between the expression of DACT2 and fibrosis degree was done with the non-parametric Spearman Rank Correlation test. *, P≤0.05.
