Table 6. Comparison of calcification indicators between patients with and without early postoperative adverse outcomes.

Variable	Early postoperative adverse outcomes		t/Z/χ2	P value
	Yes (N=15)	No (N=89)
Pericardial calcification	3 (20.0)	31 (34.8)	1.28	0.25
Calcification volume (mm2)	8,648.90±14,232.71	12,611.13±14,143.06	−0.55	0.57
Ln(calcium score +1)	7.06±3.15	8.45±2.49	0.09	0.76

Data are presented as mean ± standard deviation or number (%). Ln(calcium score +1), natural logarithm (ln) of the calcification score plus one.
