This wide range is due to the different diagnostic tools and the cut-off points used. Early diagnosis and intervention of sarcopenia are essential because of its association with poorer quality of life (QoL), higher hospitalization rates, and adverse events.

Clinical, efficacy, analytical and nutritional parameters were collected, along with functional performance measured by SPPB, frailty (FRAIL scale), risk of malnutrition (MIS scale), bioimpedance and estimation of appendicular skeletal muscle mass using Lin's formula. Ultrasound measurement of supramuscular fat, axes (X and Y) and the area of the rectus femoris muscle of the quadriceps were also included, adjusted for height and body surface area.
