Apart from the very small group of pericarditis patients (n = 3), every patient group analyzed so far displayed a comparable variation of syndecan-4 levels, with comparable minimum (min.; 2.44–6.95 ng/mL) and maximum (max; 31.28–38.72 ng/mL) levels between the groups, and an average range of 30.90 ng/mL within each group. Here, SDC4 is linked to pericarditis.
