You can request statistics to test the equality of the survival distributions for the
different levels of the factor. Available statistics are log rank, Breslow, and Tarone-
Ware. Select one of the alternatives to specify the comparisons to be made: pooled over
strata, for each stratum, pairwise over strata, or pairwise for each stratum.
Linear trend for factor levels. Allows you to test for a linear trend across levels of the
factor. This option is available only for overall (rather than pairwise) comparisons of
factor levels.

Kaplan-Meier Save New Variables dialog box
You can save information from your Kaplan-Meier table as new variables, which
can then be used in subsequent analyses to test hypotheses or check assumptions.
You can save survival, standard error of survival, hazard, and cumulative events as
new variables.
