Patient's listed for liver transplant have significant functional limitations, with a weighted mean VO2 below the threshold level required for independent living. Although heterogeneity in study designs with respect to timing, CPET variables, and cut-off values precluded the determination of CPET mortality thresholds, the studies support CPET as an objective and independent predictor of pre- and post-transplant mortality.
