Magnetic resonance cholangiography in the assessment and management of biliary complications after OLT

Table 2 Results of previous systematic reviews on the role for magnetic resonance cholangiography in assessing biliary complications after orthotopic liver transplantation

	Jorgensen et al[1]	Xu et al[55]
Goal	Biliary obstruction	All biliary complications	Subset of strictures
Pooled sensitivity	96.0% (0.92%-0.98%)	0.95% (0.92%-0.97%)	0.94% (0.88%-0.98%)
Pooled specificity	0.94% (0.90%-0.97%)	0.92% (0.89%-0.94%)	0.95% (0.88%-0.99%)
AUC	0.99	0.97	0.97
Pooled PLR	17.00 (9.4-29.6)	10.23 (6.21-16.84)	9.96 (2.52-39.36)
Pooled NLR	0.04 (0.02-0.08)	0.08 (0.06-0.12)	0.09 (0.04-0.17)

Number between parentheses represent the 95%CI. Analysis by Xu et al is stratified for the whole of complications and the subset of strictures. AUC: Area under the curve at Summary Receiving Operating Characteristic (SROC) curve; PLR: Positive likelihood ratio; NLR: Negative likelihood ratio.
