  2. Practical: Download & Setup From the course webpage download the two SPSS datasets that will be used for the practical's by clicking the right mouse button on the file name and selecting Save Target As. The two datasets are: • Survival_Ex1.sav (The example dataset used in the slides) • BC_Survival.sav (A dataset on Breast cancer survival: Data are from the Mayo clinic) • Open up both of the datasets in SPSS. • Calculate the Time variable for the Survival_Ex1.sav dataset.

  3. Practical Questions • Calculate the Life table values for Group B from the example dataset by hand, using the skeleton table below:

  4. Practical Questions The file BC_Survival.sav contains data on 1207 women who were diagnosed with breast cancer. • Produce a Life table for this data, separating those women for whom the cancer had infected the lymph nodes from those for whom it had not (ln_yesno). Split the survival time into yearly periods. • Produce a Kaplan-Meier curve for this data, separating those women for whom the cancer had infected the lymph nodes from those for whom it had not. Conduct a log-rank test to see if the survival of the two groups is significantly different. Edit the KM plot so that it would be able to ‘stand alone’ in a publication and comment on all of your results.
