AFP and neoplasm: Univariate and multivariate analyses were performed on the training group, as shown in Table 1, identifying AFP (OR = 1.94, 95% CI:1.16–3.25), tumor margin (OR = 3.04, 95%: 1.93–4.80), pseudo‐capsule (OR = 3.47, 95% CI: 2.22–5.42) and peritumoral star node (OR = 2.92, 95% CI: 1.59–5.38) as significant factors influencing Ki‐67 expression in Figure S2 (p < 0.05).
