Introduction
• JMP® 9-based system analyzes drug safety data.
• Uses enhanced and easy to understand data manipulation and
visualization techniques
• Allows medically trained personnel to explore safety data and
identify adverse events of interest for a given drug.
• New features in JMP 9 provided significant advantages
– Add-ins for menus and application distribution
– Cell colorization
– Separate windows for each object.
• Advantages of using JMP

Computational speed
Interactivity
Linking between objects
Drill-down to underlying data
Data filtering
Ability to create user-friendly interfaces.
System Overview:
• Investigates adverse events for a drug
• Input data filtered by user to focus on area of interest
• Disproportionality analysis compares Reporting Fraction (RF) of events in
different periods
 Current RF = # Current Events for one PT / Total Current Cases
 Previous RF = # Previous Events for one PT / Total Previous Cases
 FRR = Current RF / Previous RF
• Users define MedDRA coding dictionary categories to group data
• Drill-down to underlying data
 Launch safety application for a selected case
 Retrieve additional case information for selected cases from safety
application
• Visualization via barcharts, trend plots and heat map grid
MedDRA Coding Dictionary
• MedDRA - Medical Dictionary for Regulatory Activities
• Standardizes medical terminology used to classify adverse
event information
SMQ: Standard MedDRA Query
• Hierarchy:
SMQs are groupings of terms that relate
to a defined medical condition or area
of interest
SOC: System Organ Class
HLGT: High Level Group Term
HLT: High Level Term
PT: Preferred Term
LLT: Low Level Term

Tables Used by System
•
•
•
•
PT: Preferred Term summary table
HLT: High-Level Term summary table
DME: Designated Medical Events summary table
MedCat: MedDRA Category summary table for
user-defined MedDRA coding dictionary groupings
• Cell colorization used to distinguish time periods,
subtotals, trends
• Summary tables linked to main table by special JSL
code

Table Cell Acts Like a Hyperlink
•
•
•
Users click on a single cell in the Case Number column.
Safety application is launched for that Case Number
A column formula does the work:
surv_col_names = surv_dataset << get column names(string);
if (!contains(surv_col_names, "Select Logic"),
// then
surv_dataset << new column("Select Logic", character,
formula(
// Need the table names inside the formula, esp for JMP 9 because of scoping
dst = current data table();
If (Selected(),
sel_cols = dst << get selected columns;
sel_rows = dst << get selected rows;
if (islist(sel_cols),
// then
if (nitems(sel_cols) == 1 & nrows(sel_rows) == 1 &
uppercase(char(sel_cols[1])) == "CASE NUMBER",
// then
one_case_no = column(dst, "Case Number")[sel_rows[1]];
myapp_url = "http://myapp.com/abcde/caseno=" ||
char(one_case_no);
web(myapp_url);
// Launches web browser for URL
);
// end 1 col, 1 row, AER col
// end islist
);
// end if selected
"x";
// Need a dummy value for the column
);
// end forumula
);
// end new column
column(surv_dataset, "Select Logic") << hide;
// Move the cursor to the first cell
surv_dataset << go to row(1) << Clear Select << go to(:Case Number)
<< clear column selection;
); // end if Select Logic column
);
Link Two Tables Not Normally Linked
• Summary tables derived from original dataset, but
not linked
• SDF dataset  Tabulations + Calculated Columns  PT
Summary Table
• Clicking rows in PT summary table highlights all rows
in main dataset containing selected PTs
• Clicking cells in Current, Previous, Cumulative
column sections highlights rows in main dataset for
PT + corresponding time period.

MedDRA Category Builder
• Allow users to define drug-specific grouping of
data
• MedDRA categories defined by different
MedDRA levels: SOC, HLGT, HLT, PT, SMQ
• Picklists are loaded from Oracle database
• Summary table created for custom categories
• Can trend on custom categories
MedDRA Category Builder (cont)
Heat Map Grid Plot
•
•
•
•
Shows all PT/HLT values for entire time period
One PT/HLT per cell
Horizontal axis within cell shows time
Color indicates height of PT/HLT count or
reporting fraction
• Idea from last year’s Discovery conference!
Heat Map Grid Plot (cont)
• Click on cell
of interest
• Click Trend
Chart Button
Heat Map Grid Plot (trend chart)
• Trend chart created for Neutropenias HLT
Trend Chart
• Users can plot trends of PT, HLT, DME,
MedCAT values
• Y axis can be Case Count or Reporting
Percentage
• X axis can be Month, Quarter or Year
Trend Chart (cont)
• Trend chart showing 3 MedDRA
Categories by month
Conclusions
• JMP has powerful data manipulation and
visualization abilities
• With some JSL scripting it is possible to make
JMP jump!
