Meanwhile, OS also showed a trend toward worse outcomes in the EBER-negative group, albeit without significance (82.0% [95% CI, 70.3%−95.6%] vs. 89.2% [95% CI, 83.7%−95.1%], P = 0.071, Fig. 3 D).

However, this trend was attenuated and did not reach statistical significance after adjusting for tumor characteristics (HR: 0.522, 95% CI, 0.254–1.073, P = 0.077 in Model 2) and treatment-related factors (HR: 0.511, 95% CI, 0.248–1.050, P = 0.068 in Model 3).
