2. 2 Macro Overview (Plot)

3. 3 Macro Overview (Statistical Report) General Statistical Report Table Example Event/Total Median (95% CI) † Hazard Ratio (95% CI) ‡ Survival Estimates (95% CI) † P-value SASHELP.BMT Data set with no Class Variable All Patients83/1371.3 (1.0-2.9)1 Years: 58.3 (50.6-67.2) 2 Years: 42.0 (34.5-51.2) This is the footnote for this model SASHELP.BMT Data set with Class Variable Group0.0010 $ ALL24/381.1 (0.5-NE)Ref1 Years: 54.9 (41.1-73.4) 2 Years: 35.3 (22.7-54.8) AML-High Risk34/450.5 (0.3-1.2)1.47 (0.87-2.48)1 Years: 37.8 (26.0-55.0) 2 Years: 24.4 (14.6-40.9) AML-Low Risk25/546.0 (1.9-NE)0.56 (0.32-0.99)1 Years: 77.8 (67.4-89.7) 2 Years: 61.1 (49.4-75.6) This is the footnote for this model † Kaplan-Meier method; ‡ Cox model; $ Score test; This also allows an overall footnote

4. 4 Sample Dataset  SASHELP.BMT  SAS 9.3  GROUP – categorical  Acute Lymphoblastic Leukemia (ALL)  Acute Myeloid Leukemia (AML) »High Risk and Low Risk  T – time from transplant  STATUS – survival status  0=Alive  1=Dead

5. 5 Output Methods  RTF, PDF, HTML, Listing  Various file types (PNG, JPEG, TIFF, EMF, …)  DPI settings  Scalable vector graphics (9.3 and later)  From macro vs. within ODS tags

6. 6 Error Checking  Macro checks most parameter input  Custom error messages: ERROR: (Model 1: DISPLAY): TOTL is not in the list of valid values ERROR: (Model 1: DISPLAY): Possible values are LEGEND|HR|MEDIAN|TOTAL|EVENT|TIMELIST| PVAL|TABLECOMMENTS ERROR: 1 pre-run errors listed ERROR: Macro NEWSURV will cease

7. 7 Computed Statistics  1 LIFETEST procedures, up to 2 PHREG procedures  N patients, N events  Median time-to-event  Kaplan-Meier event-free rate  Cox proportional hazards ratio  Univariate and adjusted  P-value  Univariate and adjusted  Patients-at-risk numbers

8. 8 Only Required Variables Required Parameters  DATA  TIME  CENS  CEN_VL

9. 9 Dataset Transformations  XDIVISOR  CLASS  WHERE  LANDMARK

10. 10 Line and Axes Transformations  COLOR  PATTERN  Axis options  Label  Minimum  Maximum  Increment

11. 11 Plot Summary Table Options  DISPLAY  Class options  Alignment  Order  Reference  Time-points  Multiple  Unit label  P-value  Model  5 options  Stratification

12. 12 New Features  Border and Wall options  Events/N formats  Split headers  Time-point without unit  Reference text  Factor level comparison P-values

13. 13 Patients-at-Risk Table Variations  Labels  3 location options  Automatic  Values  Increment  Color  Location

14. 14 Patients-at-Risk Table Variations  Header  Alignment  Turn on/off  User specified text

15. 15 Patients-at-Risk Table Variations

16. 16 Patients-at-Risk Table Variations

17. 17 Lattice of Plots  Each cell individually customizable  Overall title  Cell titles  Overall footnote  Cell footnotes  1-S Plot

18. 18 Closing  %NEWSURV greatly reduces effort required to build a Kaplan-Meier survival plot  Graph Template Language greatly reduces effort of building publication quality plots  Goals for the future:  Add capabilities for competing risks/cumulative incidence  Add ability to enter pre-built data set to be plotted
