a
Based on organs that vendor identified as driven.
b
Derived from transportation vendor data.
c
P ≤ .05 (2-sided).
d
Derived from Organ Procurement and Transplant Network data.
e
P ≤ .001 (2-sided).
f
Based on organs that vendor identified as flown.
g
P ≤ .01 (2-sided).
h
Based on all observations. Some organs had other travel modalities (n = 4).
