TG and neoplasm: Statistically considerable variations in the maximum tumor diameter (U=2495.50, P=0.021), the number of metastatic lymph nodes (U=2313.50, P=0.004), the size of metastatic lymph nodes (U=2113.50, P=0.003), metastatic lymph node ratio (U = 2111.50, P = 0.004), metastatic lymph node location (χ2 = 9.20, P = 0.002) and ps-Tg level (U=1011.00, P< 0.001) between the two groups.
