The images below show the result for clicking on the various output icons:
For this analysis, the number of groups for the edema categorical (group) variable is k=3. Since the logrank test is based on k-1 degrees of freedom, the calculated test statistic of 118.91 is compared with a quantile value from a 2 degree-of-freedom chi-squared distribution when the tail probability of 0.05, which is 5.99. Since the calculated test statistic of 118.91 is significantly greater than 5.99, we reject the null hypothesis that the survuval curves are not different, and accept the alternative hypothesis that the curves are significantly different from one another without any overlap.
