Table 1. Clinical data on both study groups.

  Group 1 (n=506) ≤21 days Group 2 (n=501) >21 days P-value
Storage time (mean±SD) 16.8±3 days 24.4±2,7 days <0.001
Post-mortem time (mean±SD) 27±15 days 28±17 days 0.98
Donor age (mean±SD) 64±17 years 63±18 years 0.47
Patient age (mean±SD) 59±19 years 58±19 years 0.50
Follow-up (median, lower, and upper quartile) 540 (264, 848) days 509 (264, 809) days 0.34
Percentage of normal risk patients 31% (n=159) 32% (n=158) 0.97
Percentage of matched grafts (≤2 mismatches)a 34% 33% 0.83
Immune reaction after 2 yearsb (percentage, 95% confidence interval) 26.5 (21.6–31.2)% 20.1 (15.5–24.5)% NA
Immune reaction after 3 yearsb (percentage±95 confidence interval) 32.6 (25.9–38.6)% 25.9 (18.9–32.3)% NA

There was a statistical significant difference regarding the occurrence of endothelial immune reactions between the two groups. All other parameters were not statistically significantly different.

a

Matching did not distinguish between HLA class I and HLA class II.
