Serum total adiponectin level was inversely correlated with BMI (Fig 2A, S1 Table; r = − 0.344, p = 0.002) and the tumor diameter on radiographic assessment was slightly correlated with the serum total adiponectin level (Fig 2B, S1 Table; r = 0.286, p = 0.011). The gene discussed is ADIPOQ; the disease is neoplasm.
