The assumption of proportional hazards was verified using scaled Schoenfeld residuals.
After excluding those with a history of heart disease, stroke, or malignant tumor, 1,618 subjects(832 men and 786 women)who had completed the questionnaire were used in the analyses with Cox's proportional hazards model.
Therefore, Cox proportional hazards analysis was used and all continuous variables were modeled linearly.

Strata in the Cox proportional hazards modelWhen the proportional hazards hypothesis does not hold, the model can be stratified.
The proportional hazards model has been developed by Cox(1972) in order to treat continuous time survival data. However, frequently in practical applications, some observations occur at the same time. The classical partial likelihood cannot be applied. With XLSTAT, you can use two alternative approaches in order to handle ties:.
