Associations of clamping time with patient and graft survival and death-censored graft survival
| Time of Clamping | N (%) | Model Comparing am with pm Clamping (for Midnight–Noon, n=3094; for Noon–Midnight, n=1678) |
Model Using 6 pm–Midnight as Reference (for 6 pm–Midnight, n=1139; for Midnight–6 PM, n=3663) |
