Although correlation coefficient for tissue and serum adiponectin levels was tolerable (r = 0.56, P < 0.001), the differences in adiponectin levels between tumor tissue and control tissue were insignificant (4.63 ± 4.73 μg/g of tissue versus 3.97 ± 2.29 μg/g of tissue, P = 0.105). The gene discussed is ADIPOQ; the disease is neoplasm.
