Sensitivity analysis of association (adjusted proportion ratio and 95% CI) between knowledge score and attitude and behavior toward deceased organ donation after multiple imputation.

Outcomes	Knowledge score
	Lowest tertile (n=534)	Middle tertile (n=446)	Highest tertile (n=264)
Organ donor registration*	1 [reference]	0.92 (0.75–1.13)	0.99 (0.79–1.23)
Willingness to donate organs after death**	1 [reference]	1.19 (1.01–1.41)	1.39 (1.15–1.67)

Multiple imputation for missing covariate variables was used.

^*Modified Poisson regression analysis adjusted for age, sex, occupation (medical or non-medical staff), work experience in organ transplantation, family discussion about deceased organ donation, and willingness to donate organs after death;
