Test of equality of survival distributions for the different levels of Treatment arm. That is all SPSS gives You then conduct Cox Proportional Hazard regression analysis using these variables to compare survival times for those with and without the exposure. Finnish / Furthermore, the Cox regression model extends survival analysis methods to assess simultaneously the effect of several risk factors on survival time.

In the context of an outcome such as death this is known as Cox 2020-04-16 · Variables with positive coefficients (the B values) are associated with increased hazard and decreased survival times, i.e. as the predictor increases the hazard of the event increases and the predicted survival duration decreases. Negative coefficients indicate decreased hazard and increased survival times.

Cox regression (or proportional hazards regression) is method for investigating the effect of several variables upon the time a specified event takes to happen. In the context of an outcome such as death this is known as Cox 2020-04-16 · Variables with positive coefficients (the B values) are associated with increased hazard and decreased survival times, i.e.
