SAS Tools for Creating Clinical Trial Graphs

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. 

There are a number of SAS procedures that help to build the graphics most common to clinical trial reporting. The following table describes which SAS procedures make which graphs. 

Box plot PROC BOXPLOT, PROC GPLOT, or PROC UNIVARIATE 

Kaplan-Meier plot PROC LIFETEST or PROC GPLOT 

Note that for box and survival plots, PROC GPLOT is listed as an alternative. Although PROC BOXPLOT and PROC LIFETEST produce excellent graphs by themselves, sometimes it is necessary to make modifications to the output in a way that these procedures cannot handle directly. When modifications are needed, PROC GPLOT is an excellent choice. Also note that PROC REG and PROC UNIVARIATE are listed as options for scatter plots and box plots, respectively, as they can be useful in producing lower-resolution graphics for statistical appendices.
