Intra-class correlation coefficient (ICC) for tumour budding

ICC 95% CI
TB-A1 0.646 0.529–0.763
TB-A2 0.669 0.556–0.778
TB-A1 (cut-off 10) 0.650 0.536–0.764
TB-A2 (cut-off 10) 0.698 0.596–0.800

ICC is calculated for continuous data and for data divided into categories as low-budding (< 10 buds) and high-budding (≥ 10 buds) (n = 129)
