Non-parametric bivariate correlation coefficients between serum oxylipin or N-acylethanolamine levels and the age, physical activity, pain duration (Achilles tendinopathy patients), BMI, blood lipid status, BDNF and sTNFR1 levels in the dataset

Abbreviations: tMets, physical activity, estimated in metabolic equivalent hours per week; PaD-A, pain duration for the patients with Achilles tendinopathy; BMI, body mass index; Chol, serum cholesterol; TG, serum triglycerides; HDL and LDL, serum high and low density lipoprotein; BDNF and sTNFRI, serum levels of brain-derived neurotrophic factor (BDNF) and soluble tumour necrosis factor receptor I, respectively. Significance levels are: *P.
