| All subjects (N=783), 651 deaths | <55 years (N=387), 258 deaths | ≥55 years (N=396), 393 deaths | ||||
| HR (95% CI) | p-value | HR (95% CI) | p-value | HR (95% CI) | p-value | |
| Low CMV tertile | Ref. | Ref. | Ref. | |||
| Medium CMV tertile | 1.15 (0.94–1.40) | 0.187 | 1.35 (0.99–1.85) | 0.059 | 0.87 (0.66–1.14) | 0.299 |

Cox model adjusted for sex, age, body mass index, level of education, smoking status and pack-years. Total numbers are lower than the 806 included participants because some individuals had missing information on covariates. HR: hazard ratio.
