Comparing Different procedural time intervals between patients who developed surgical site infection (SSI) vs those who did not develop SSI

Covariate	SSI N = 14 (%)	No-SSI N = 64 (%)	P-value
Interval to T1 in hours (Mean ± SD)	1.22 ± 0.87	0.97 ± 0.55	0.17
T1 Interval less than 30 Minutes	0 (0)	2 (3.1)	0.51
T1 Interval less than one hour	7 (50)	41 (64)	0.33
T1 Interval less than 1.5 hour	11 (78.6)	59 (92.2)	0.13
Interval to T2 in hours (Mean ± SD)	3.09 ± 1.12	2.32 ± 0.98	0.01
Interval to T3 in hours (Mean ± SD)	5.74 ± 1.69	4.68 ± 1.83	0.05
Interval to T4 in hours (Mean ± SD)	7.35 ± 1.97	6.01 ± 2.11	0.03

T1: before skin incision, T2: before starting CPB, T3: 1 hour after starting CPB, T4: immediately before skin closure.
