Over 9 days – the mean duration of a motorcycle rally – the net effect of motorcycle rallies resulted in 14% more organ donors and 19% more transplant recipients per day during rally dates versus non-rally dates (IRR 1.14, 95% CI 1.01-1.30, P=0.04).
“During motorcycle rally weeks in distant regions not containing motorcycle rallies, there was no increase in the number of organ donations or transplants, suggesting that our observed main effect was associated with the rallies rather than other temporal factors such as vacation travel,” the authors wrote.
