As shown in the forest plots, CD147 was significantly associated with TNM stage (TIII/TIV vs TI/TII: combined OR 3.60, 95% CI 1.85–7.01) (Figure 4), depth of invasion (T3/T4 vs T1/T2: combined OR 2.04, 95% CI 1.25–3.33) (Figure 5), lymph node metastasis (positive vs negative: combined OR 2.35, 95% CI 1.14–4.86) (Figure 6), and distant metastasis (positive vs negative: combined OR 4.78, 95% CI 1.43–16.00) (Figure 7). The gene discussed is BSG; the disease is metastatic malignant neoplasm in the lymph nodes.
