Mean concentrations (± standard error of the mean; SEM) of N-terminal propeptide of procollagen type I (PINP), serotonin (5-HT) and substance P (SP) in women with trapezius myalgia (TM; blue bars) and in healthy controls (CON; grey bars) based on pooled dialysate (from t = 120 min and t = 140 min; see text for details). Please note that the number of subjects in CON (n = 6) for SP was low due to lack of dialysate when this analysis was performed.
