CD8A and cervical squamous intraepithelial neoplasia: Corresponding analysis of overall survival (OS) revealed that CD8+ density, but not MMR-D/POLE mutation or CIN, was associated with significantly reduced mortality (multivariable-adjusted HR = 0·93; 95% CI = 0·87–0·99, P = 0·024) (Table 1, Fig. 2b).
