For example, in the low-risk group, 3 year recurrence-free probabilities for tumours with CD8+ cell density at the 25th and 75th centiles were similar at 90.2% (95% CI 87.8–92.7%) and 90.1% (95% CI 87.7–92.71%), respectively, while the corresponding proportions in the high-risk group were 58.3% (95% CI = 52.8–64.4%) and 68.6% (95% CI = 63.1–74.6%) (Table 2, Fig. S2). Here, CD8A is linked to neoplasm.
