TG and neoplasm: As shown in Table 2, the results revealed that male (OR: 2.10, 95% CI: 1.49–2.97, P < 0.001), age ≥45 (OR: 0.44, 95% CI: 0.32–0.60, P < 0.001), PS-Tg level ≥31.650 (OR: 1.88, 95% CI: 1.32–2.68, P < 0.001), ETE negative (OR: 0.57, 95% CI: 0.36–0.92, P = 0.02), maximum tumor size >1 cm (OR: 6.47, 95% CI: 4.51–9.37, P < 0.001), and multifocality positive (OR: 2.85, 95% CI: 2.01–4.04, P < 0.001) remained independent predictive variables for CLNM.
