Characteristics of Subjects in the Study

The script initializes the Output Delivery System (ODS) to produce graphical output. It defines a statistical graph template (`STATGRAPH`) named `Fig_8_0_PatientProfile` using `PROC TEMPLATE`. This template arranges a scatter plot (cholesterol vs. systolic blood pressure) and bar/box plots (average weight, diastolic blood pressure by cause of death) in a lattice layout. Finally, `PROC SGRENDER` is used with the `sashelp.heart` dataset to apply this template and generate the resulting graph as an image.

Data Analysis

Type : SASHELP

The script uses the standard `sashelp.heart` dataset from SAS, which is provided with the SAS installation and does not require an external source or internal creation.

1 Code Block

ODS Setup

Explanation :
This block initializes the Output Delivery System (ODS) options. It defines an output path for images (`gpath`), image resolution (`dpi`), and configures ODS output for HTML with an `htmlblue` style. The `ods html close;` command closes the default HTML destination to avoid conflicts when generating subsequent graphs.

2 Code Block

PROC TEMPLATE

Explanation :
This block defines a statistical graph template (`STATGRAPH`) named `Fig_8_0_PatientProfile`. The template creates a lattice layout (`layout lattice`) with two columns. The first column contains a scatter plot (`scatterplot`) of cholesterol versus systolic blood pressure, grouped by sex. The second column is another lattice superimposing a bar chart (mean weight by cause of death and sex) and a box plot (diastolic blood pressure by cause of death and sex). Various style attributes are applied to enhance the readability and aesthetics of the graph.

3 Code Block

PROC SGRENDER

Explanation :
This block activates the `ods listing` destination and configures `ods graphics` with specific dimensions (`width`, `height`) and an image name (`imagename`). `PROC SGRENDER` is then used to generate the graph by applying the previously defined `Fig_8_0_PatientProfile` template to the `sashelp.heart` dataset. The result is a graphic image encapsulating the template.

ODS Cleanup

Explanation :
This block resets the global ODS titles and footnotes, ensuring they do not persist for subsequent ODS outputs.
