Figure 2.

(A) Cumulative percentage of donated pancreata. The donated pancreata with NAIDS ≥65 consisted of 60% of all GMP-grade islet isolation products (n = 198); those with NAIDS ≥80 only consisted of 20% of all isolations. (B) Correlation of NAIDS and islet yield. A significant positive correlation appears between NAIDS and islet yield (n = 198, Spearman's rank correlation coefficient = 0.379, p < 0.001). (C) Temporal trend in either islet yield or NAIDS. Islet yield is not in a significant linear association with isolation date, neither is NAIDS (n = 119, p > 0.05). Xth case means the number of isolation batch categorized by isolation date (e.g., fifth case of islet isolation sorted by isolation date). NAIDS, North American Islet Donor Score; IEQ, islet equivalent number; GMP, good manufacturing practice.
