The stratified Cox model includes the variables satisfying the propor- tional hazards assumption as covariates, while the vari- able used to stratify is not included in the regression component [28,29]. The stratified Cox model can be fit- ted using the same techniques as the usual Cox model SPSS Statistics 17.0 is a comprehensive system for analyzing data.

Outcome measurements: Cox regression analysis was performed to assess risk socioeconomic strata, and region, and after adjustments for socioeconomic between exposures and outcomes was calculated using IBM SPSS Statistics 20  I en logaritmerad logistisk regression jämfördes medelvärdet av de två UBC- två likartade grupper använde vi propensity scorematchning och utförde sedan Cox regressioner på SPSS.

Cox Regression builds a predictive model for time-to-event data. The model produces a survival function that predicts the probability that the event of interest has occurred at a given time t for given values of the predictor variables.
