Contemporary incidence and risk factors of post transplant Erythrocytosis in deceased donor kidney transplantation

Table 3 Association of Post Transplant Erythrocytosis and patient & allograft survival

Outcome	Exposure	Number of event (%)	Mean event rate per 1000 patient year (95% CI)	Unadjusted Hazard Ratio (95% CI)	Adjusted 1 Hazard Ratio (95% CI)	Adjusted 2 Hazard Ratio (95% CI)
Death	No PTE (n = 1048)	103 (10%)	23.5 (19.4, 28.5)	1 (ref)	1 (ref)	1 (ref)
Death	PTE (n = 75)	4 (5%)	18.4 (6.9, 48.9)	0.88 (0.32, 2.41)	1.01 (0.50, 2.07)	1.07 (0.52, 2.20)
All-cause graft failure	No PTE (n = 1048)	228^a (22%)	52.0 (45.6, 59.2)	1 (ref)	1 (ref)	1 (ref)
All-cause graft failure	PTE (n = 75)	8 (11%)	36.7 (18.4, 73.4)	0.81 (0.40, 1.64)	1.07 (0.39, 2.94)	1.29 (0.46, 3.63)
Death-censored graft failure	No PTE (n = 1048)	131 (12%)	29.9 (25.2, 35.4)	1 (ref)	1 (ref)	1 (ref)
Death-censored graft failure	PTE (n = 75)	4 (5%)	18.4 (6.9, 48.9)	0.72 (0.27, 1.98)	0.94 (0.35, 2.60)	0.94 (0.34, 2.60)

Adjusted 1 is adjusted for donor Kidney Donor Profile Index (KDPI)
Adjusted 2 is adjusted for donor KDPI, cold ischemia time and the following recipient variables: age (years), black race, sex, previous kidney transplant, number of human leukocyte antigen mismatches, panel reactive antibody (%), body mass index (kg/m2), preemptive transplant and transplant center
^aThere were 6 recipients who developed graft failure and then died. This explains the difference between the number of all-cause graft failure (228) and the sum of numbers of death (103) and death-censored graft failure (131)
