*Increased ITU stay was associated with lower handgrip strength (right (27 ± 6 and 36 ± 12 kg p < 0.01) and left (27 ± 7 and 35 ± 12 kg p = 0.01)

†There was a correlation between grip strength and day of discharge post-transplant (r = -0.41, P = 0.01). There was no association between grip strength and length of time spent on ventilatory support post-transplant (r = -0.250) or length of time spent on the intensive care unit post-transplant (r = -0.112)

* Survival plot from time of listing to transplant or death (not for grip strength).
