Table 6 Weighted mixed-effect on transplant center linear regression of cold ischemia time in the propensity-matched cohort

Variables	Effect-hours (95%CI)	Effect-minutes (95%CI)	P value
Biopsy performed	+0.70 (0.58-0.81)	+42 (35-49)	< 0.001
Distance between donor and recipients’ hospital miles	+0.0035 (0.0034-0.0037)	Approximately 21 minutes per 100 miles	< 0.001
Sharing
Local	Reference
Regional	+2.9 (1.8-3.1)	+174 (108-186)	< 0.001
National	+4.2 (4.0-4.4)	+252 (240-264)	< 0.001

Estimates represent the effect of biopsy and other covariables on cold ischemia time, expressed in both hours and minutes. All donor covariables from Table 5 were included in the model for controls; only biopsy performed, distance, and organ sharing are shown here. CI: Confidence interval.
