Longitudinal change in the adjusted relative incidence of living kidney donation during the period 2005 and 2015 in women and men, stratified by donor relation

Donor Relation	Women	Men
	IRR (95% CI)	IRR (95% CI)
All	0.95 (0.84 to 1.07)	0.75 (0.68 to 0.83)a
Spousal	0.91 (0.75 to 1.09)	0.78 (0.62 to 0.99)a
Related	0.68 (0.60 to 0.76)a	0.53 (0.48 to 0.59)a
Unrelated	1.02 (0.88 to 1.18)	0.83 (0.71 to 0.96)a

IRR refers to the relative incidence of living kidney donation in 2015 relative to 2005, on the basis of a multilevel Poisson regression model adjusted for donor- and population-level age, race, ESRD rate standardized for race and age, and RUCA, clustered by state of residence. Overall, men had a 25% decline in living donation between 2005 and 2015, with an IRR of 0.75.
