“…The magnitude of differences in the measured concentrations for particular adipokines was variable. Namely, the values reported by various research teams for resistin [ 113 , 124 ], ghrelin [ 121 , 139 ], and nesfatin-1 [ 140 , 141 ] show a 2- to 9-fold variation in magnitude, while for adiponectin [ 113 , 116 ], leptin [ 119 , 121 ], visfatin [ 113 , 122 ], chemerin [ 146 , 147 ], apelin [ 141 , 148 ], adropin [ 151 , 152 ], copeptin [ 130 , 155 ], and omentin [ 156 , 157 ], they is a 20- to 50-fold variation in magnitude, and for leptin, an 80-fold variation in magnitude. The values presented for irisin are extremely variable, namely from 12 to 7740 ng/mL, with a 645-fold variation in magnitude [ 127 , 128 , 131 , 136 , 137 ].…”
