AFP and neoplasm: Univariate analysis of the factors associated with progression-free survival (Table 4) revealed the following significant prognostic factors: high hsa_circ_0005986 expression (HR, 0.492; 95% CI, 0.317–0.763; p = 0.002), multiple tumors (HR, 2.592; 95% CI, 1.666–4.032; p < 0.001), tumor size < 5 cm (HR, 5.239; 95% CI, 3.210–8.550; p < 0.001), vessel invasion (HR, 6.001; 95% CI, 3.717–9.686; p < 0.001), AFP level > 400 ng/mL (HR, 3.769; 95% CI, 2.407–5.903; p < 0.001), poor CTP class (HR, 3.257; 95% CI, 1.886–5.624; p < 0.001), and curative treatment (HR, 0.164; 95% CI, 0.101–0.267; p < 0.001).
