Demographics Distribution
This report displays the Demographic characteristics for a clinical study. It accomplishes this using both a graphical histogram display (Demographic Details) and a tabular display (Demographic Tables). Optionally, but not by default, it can display statistical comparisons as well.
Report Description
Running this report with the Nicardipine sample setting using the default options generates the output shown below.
The Demographics Distribution report initially shows two sections Demographic Characteristics and Distributions.
Demographics Characteristics
Presents histograms for available demographic characteristics such as age, treatment, sex, race, ethnicity, and Study Site Identifier, by default. Click 
in the Options panel to add additional histograms.
This section contains the following elements:
| • | One or more Histograms. |
The height (or length) of each bar is an indication of the number of subjects exhibiting each demographic characteristic.
You can change how your data are presented in the histograms using the Histogram Options, which can be viewed by clicking 
for each set of histograms and selecting Display Options.
Quantiles and summary statistics are provided for continuous variables like Age, and frequencies are provided for categorical variables like Sex. These can be viewed by clicking for each set of histograms and selecting Display Options.
See Distribution for more information.
Treatment Comparisons
This report performs aone-way ANOVA (analysis of variance) to detect statistical differences for continuous demographic variables (e.g. Age) and contingency analyses for character/categorical variables (e.g. sex, race, and study site) by the treatment variable specified in the Optionspanel.
The One-way Plot above shows the distribution subjects by age for each of the two treatment arms. The analysis statistics are listed in the tables below the plot.
The Mosaic Plots for sex and race by treatment arm are graphical representation of a two-way frequency table or contingency table (shown below their respective plots) , divided into colored rectangles. There is one rectangle for each demographic group for each treatment arm. The area of each rectangle is proportional to the proportions of each demographic group in each treatment arm.
Options
This panel enables you to select the demographic variables used to create distributions, specify the number of decimal places to display and perform treatment comparison analysis for the demographic groups.
Create additional distributions for selected variables
This option enables you to add or remove demographic variables from DM from the distributions.
| 8 | Click  to open the Add window shown below: |
| 8 | Select one or more variables and click |
| 8 | To remove one or more distributions, highlight the variables to be deleted and click  . |
| 8 | To rearrange the order of the distributions, select a variable and click either  or  . |
Number of Decimals to Display for Numeric Results
Use this option to specify the number of decimals to include in the plots and tables of numerical results.
Perform treatment comparison analysis for demographic variables.

Methodology
No testing is performed. Analysis is restricted to tabulating counts/percentages of subjects' demographic data.
