ROC-curves presenting sarcopenia parameter classification of grip strength and chair stand cut-offs for probable sarcopenia. a = classification of grip strength-based probable sarcopenia by walkspeed, TUG and ALMheight2. b = classification of chair stand-based probable sarcopenia by walkspeed, TUG and ALMheight2. AUC = Area Under the Curve, ALMheight2 = Appendicular Lean Mass relative to squared body height, TUG = Timed-Up-and-GO test. The Tromsø Study 2015-2016
