Receiver operating characteristics (ROC) curves performance for total SPPB score (dotted line), SPPB subtest for gait speed (solid line) and SPPB subtest for sit-to-stand (dashed line) in assessing sarcopenia in men (M) (a–c) and women (F) (d–f) aged ≥60, according to each AWGS19 physical performance definition for sarcopenia, including gait speed (GS) (a,d), sit-to-stand (STS) (b,e) and Short Physical Performance Battery (SPPB) (c,f). Respective area under the ROC curve (AUC) and 95% CI are presented
