Common Clinical Trial SAS/GRAPH Procedures 205 Using the Annotate Facility for Graph Augmentation 206 Sample Graphs 207... 

SAS provides many tools for creating graphical displays of clinical trial data. The majority of these tools can be found in SAS/GRAPH software, and those are what we explore here. 

The Annotate data set is then fed to a SAS/GRAPH procedure and gets processed along with the SAS/GRAPH code. 

Note that PROC BOXPLOT uses SAS/GRAPH statements such as GOPTIONS and SYMBOL statements. There is a vast array of display options in the PROC BOXPLOT PLOT statement not used here. You may want to investigate those options if you decide to enhance the box plot further. 

Here is the SAS program that creates the preceding graph. It is a bit complex, because SAS/GRAPH does not provide horizontal box plots and this is typically what is desired for odds ratio plots. So, this sample program relies extensively on the Annotate facility to produce the plot. Notes follow the program. 

Although all of the examples in this chapter export graphs to Microsoft Windows CGM files, SAS/GRAPH has the ability to export graphs to many different destinations. The two basic ways to export SAS/GRAPH output are with SAS graphics drivers and with an ODS destination specification. 

To change the graphics file you want to produce, you only need to make a minor adjustment to the FILENAME and GOPTIONS statements. Just change the shaded text below in your SAS/GRAPH code to the appropriate settings ... 

When should you use SAS/GRAPH That is a question that deserves some attention. SAS/GRAPH is a wonderful choice for graphics if the following are true ... 

Quick Results with SAS/GRAPH Software by Arthur L. Carpenter and Charles E. Shipp... 

The examples in this book focus primarily on the tools within SAS/GRAPH, SAS/STAT, and Base SAS, including the SAS macro language and PROC SQL. The examples were developed using SAS 9.1.3, but the vast majority of the examples will run with other versions of SAS as well. Please note that the data that drive the examples in this book are obtained through INPUT statements with DATALINES data. This is done only for illustrative purposes and does not mean that you should expect to obtain your clinical data in this fashion.
