Interaction term and p-value evaluating whether age modified the relationship between ILDKT and post-transplant outcomes

Sensitivity analysis excluding PLNF: interaction term=_0.570.76_1.01, p=0.06

Older ILDKT recipients have a 2.07-fold higher mortality risk compared to younger ILDKT recipients. When compared to younger CLDKT recipients, younger ILDKT have a 51% increased mortality risk (aHR: _1.311.51_1.75, p<0.001). Among older recipients, this risk is attenuated and not statistically significant (aHR: _0.891.14_1.45, p=0.3); the interaction between age and incompatibility status was not statistically significant (p interaction=0.052).
