Table 2. Intraoperative variables.

Variables	Non-AF group (n = 315)	AF group (n=143)	p value
CPB use	136 (43.2%)	99 (69.2%)	< 0.001
CPB time (min)	87.94 ± 27.98	94.48 ± 35.05	0.116
LITA use	306 (97.1%)	135 (94.4%)	0.151
Complete revascularization	299 (94.9%)	137 (95.8%)	0.682
Number of distal bypass	3.43 ± 0.87	3.69 ± 0.77	0.007

AF, atrial fibrillation; CPB, cardiopulmonary bypass; LITA, left internal thoracic artery.

Data expressed as mean ± standard deviation for continuous variables or number (%) for categorical variables.

Independent samples t-test was used for comparing CPB times.

Mann Whitney U test was used for comparing numbers of distal bypass.

Categorical variables were compared using chi square tests.
