ADIPOQ and neoplasm: Although circulating adiponectin level was not significantly associated with the overall survival (OS) (p = 0.2102) (Figure 1A), the high adiponectin concentration group clearly showed better prognosis in metastasis-free survival (MFS) compared with the low adiponectin concentration group (p = 0.0106, Figure 1B), and such result was also confirmed in a univariable analysis including tumor grade, recurrence, and blood adiponectin level (Hazard-Ratio (HR): 0.282; 95% CI: 0.100–0.796; p = 0.005) (Table 2).
