Correlations between Unified Parkinson’s Disease Rating Scale (UPDRS) and Addenbrooke’s Cognitive Examination (ACE) scores with cytokine levels. (A,B) Correlations between UPDRS and interleukin (IL)-1beta (r=−0.285, P=0.002), IL-2 (r=−0.220, P=0.018) and IL-4 (r=−0.217, P=0.019), and between UPDRS and IL-6 (r=0.208, P=0.025) and tumour necrosis factor (TNF)-alpha (r=0.168, P=0.071). (C,D) Correlations between the ACE score and IL-1beta (r=0.494, P=0.000), IL-2 (r=0.485, P=0.000) and IL-4 (r=0.540, P=0.000), and between the ACE and IL-6 (r=−0.343, P=0.000) and TNF-alpha (r=−0.253, P=0.006).
