ANCOVA regression models will be used to calculate mean scores differences with 95% confidence interval (CI) with HRQOL scores as outcomes. Cox proportional hazard regression models will be used to assess the association between exposure and mortality after surgery. Kaplan Meyer survival curves will be calculated and log rank test will be tested. All above mentioned regression models will be adjusted for predefined confounders.
