ALB and sarcopenia: It is important to note that some researches have shown MCI decreases at the same time prior to death as nutritional indices, including normalized protein catabolic rate, serum albumin, phosphate, and creatinine [57, 58].Thus, based on earlier findings [9, 12, 13] and the current study, MCI appears to be a valuable and easy access marker of lean body mass and deserves monitoring its change over time, which facilitates early detection of muscle wasting or sarcopenia trends, and offers intervention opportunities to stop, delay, or even reverse such harmful effect.
