Table 2. The relationship of DACT2 expression in myocardium with cardiac rhythm of patients with valvular heart disease.

Variable	Weak	Strong	P
SR	1 (3.6%)	9 (32.1%)	0.022*
AF	10 (35.7%)	8 (28.6%)

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. P value comparison between the 2 groups with the independent Student’s t-test or χ²-test. *, P≤0.05. SR, sinus rhythm; AF, atrial fibrillation.
