ICC analysis of continuous variables demonstrated a consistently low agreement: age (ICC 0.013, 95% CI –0.035 to 0.060), tumor size (ICC 0.029, 95% CI –0.021 to 0.078), number of metastatic lymph nodes (ICC 0.031, 95% CI –0.019 to 0.081), number of harvested lymph nodes (ICC 0.025, 95% CI –0.025 to 0.075), and Ki67 expression (ICC 0.027, 95% CI –0.023 to 0.077). The gene discussed is MKI67; the disease is neoplasm.
