Frequency (%) for categorical variables and median (IQR) for contentious variables.
Equivalent to OR (95% CI) of male-to-male group.
Equivalent to OR (95% CI) of female-to-male group.
OR of male-to-female group can be estimated by multiplying of donor sex variable, donor-recipient sex-mismatch variable, and the interaction between donor sex and donor-recipient sex-match variable (supplemental Tables 3 and 4).
