| Cox proportional hazards regression model was performed to assess risk factors for overall survival. Positive coefficients imply that the risk of death increases with increasing values of risk factor. The p values reflect the role of chance in these findings. The relative risk attributable to a risk factor can be estimated from the regression coefficient. | ||||
