Reports | Frequencies

Frequencies
This report identifies unusual frequencies across the entire study or by study visit. This analysis is typically used on categorical variables, though an analysis on continuous outcomes can identify an over- or under-representation of certain values at a site compared to other sites.
Note : JMP Clinical uses a special protocol for data including non-unique Findings test names. Refer to How does JMP Clinical handle non-unique Findings test names? for more information.
Report Results Descriptions
Running this report with the Nicardipine sample setting generates the report shown below.
The Report contains the following elements:
Frequencies Volcano Plot
Shows a volcano plot used to determine the deviation of the proportion of findings frequencies at each site with the overall proportions for the findings across the whole study.
One Data Filter .
Enables you to subset subjects based on country of origin, study site and/or Test. Refer to Data Filter for more information.
The volcano plot is used to determine the deviation of the proportion of findings frequencies at each site with the overall proportions for the findings across the whole study. Each “bubble” represents a single Findings test for a specific site, which is compared to a reference (all other sites).The X axis represents the maximum difference in proportions between each value of the Findings test between the site and the reference set (all other sites).
You can mouse over points of interest to see their labels or select points by dragging a mouse rectangle over them (as shown above). Selected rows are highlighted in other plots and you can also then click on various Down Buttons for further analyses on those specific sites. For example, if you click , the following opens with comparisons of sites 18 and 40 with all sites not site 18 or 40, respectively.
ECG Test Results
Displays histograms summarizing ECG findings across the study.
This section contains the following elements.
Data Filter : Enables you to filter data based on study site and country.
Distributions : Displays histograms showing distribution of ECG findings across study sites, tests, and visit numbers, study sites, categories, and tests.
Laboratory Test Results
Displays histograms summarizing lab test findings across the study.
This section contains the following elements.
Data Filter : Enables you to filter data based on study site and country.
Distributions : Displays histograms showing distributions of laboratory test findings across study sites, tests, and visit numbers, and tests.
Vital Signs
Displays histograms summarizing vital signs findings across the study.
This section contains the following elements.
Data Filter : Enables you to filter data based on study site and country.
Distributions : Displays histograms showing distribution of vital signs findings across study sites, tests, and visit numbers,
Action Buttons
Action buttons, provide you with an easy way to drill down into your data. The following action buttons are generated by this report:
Show Sites : Shows the rows of the data table for the selected points from the volcano plot . Clicking opens the following table:
Frequency Bar Chart : Select points on the volcano plot and click to display a bar chart for each point showing the proportions of each value of the Findings Test for the site as compared to the distribution of all of the other sites combined.
Profile Subjects : Select subjects and click to generate the patient profiles. See Profile Subjects for additional information.
Show Subjects : Select subjects and click to open the ADSL (or DM if ADSL is unavailable) of selected subjects.

Click the Options arrow to reopen the completed report dialog used to generate this output.
Click the gray border to the left of the Options tab to open a dynamic report navigator that lists all of the reports in the review. Refer to Report Navigator for more information.
Methodology
This report compares the observed distribution of categorical tests with each site compared to all other sites taken together as a reference, ordering by numeric equivalent if available. For example, if character variable lists none, mild moderate, severe, very severe with corresponding numeric value ( xxSTRESN ) listed as 0, 1, 2, 3, 4, the intended order of the column variable levels are maintained.
