Despite increasing recognition of FTR as a quality metric, evidence in liver transplantation remains limited. Sarcopenia, early allograft dysfunction, and socioeconomic disparities may contribute to FTR, but current findings are insufficient for robust conclusions. Future research should aim to standardize FTR definitions and conduct multicenter prospective studies to clarify modifiable factors and improve post-transplant outcomes.
