PD-TD + indeterminate: Parkinson’s disease tremor dominant and indeterminate; PD-PIGD: Parkinson’s disease postural instability/gait difficulty; RMR: resting metabolic rate; RMR/KG: resting metabolic rate per kilogram of total body weight. All values are expressed as mean ± SD or as absolute numbers and percentage. The statistics used were t-test and χ² test.
