Risk factors of biliary intervention by imaging after living donor liver transplantation

Table 5 Biliary intervention rate by anastomosis site angle¹

Variable	Total number	Number of events	Rate of events	P value	Mean time interval to events (mo)	P value
Group 1	98	30	30.6%	P < 0.001	62.1 ± 4.1	P < 0.001
Group 2	98	59	60.2%		38.5 ± 4.2

¹The groups were categorized according to the anastomosis site angle (median angle = 113.3°); group 1, angle > 113.3°; group 2, angle ≤ 113.3°.
