Handgrip Strength and Anthropometry in Parkinson’s Disease at Diagnosis
Table 5
Multiple linear regression models, B-value, and value in patients (N = 75) and controls (N = 24) for ECW/ICW ratio, TBW (ECW + ICW, l), FFMI, and FM (%). Interaction between cortisol and phosphate is excluded (not significant).

UPDRS = Unified Parkinson’s Disease Rating Scale. 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.
