UPDRS = Unified Parkinson’s Disease Rating Scale. H&Y = Hoehn & Yahr. MNA = Mini Nutritional Assessment. PAL = physical activity level. HGS = handgrip strength (kgf). BMI = body mass index (kg/m2). ECW = extracellular water, l. ICW = intracellular water, l. TBW = total body water (ECW + ICW). FFMI = fat-free mass index (kg/m2). FM (%) = fat mass percent. The significance level is 95% CI ∗p<0.05.
