Table 5 Cox proportional hazards model estimates of the association between period (war and/or pandemic) and survival beyond age 50y
Model (Number of individuals at risk, number of mortality events) | Period | Adjusted† hazard ratio (95% confidence interval) | p-value for association | p-value for proportional hazards assumption‡ | p-value for likelihood ratio comparing model to null | ||

War | 2.48 (0.98 to 6.30) | 0.055 | |||||
