White Papers to Fill the Gaps of Standardization of Tables, Figures, and Listings (Creating Standard Targets)
Analyses and Displays for Vital Signs, ECG, and Laboratory Analyte Measurements

White Paper 2 – Under 1st Round Review!
White Paper 1 – Finalized October 2013
Conclusion:Industry standards have evolved over time for data collection
(CDASH), observed data (SDTM), and analysis datasets (ADaM). Development of standard tables and figures with associated analyses
is the next step! Having an organized process for shared learning of improved
methodologies can lead to earlier safety signal detection and better characterization of the safety profile of our products.

OBJECTIVE
The objective of this poster is to receive feedback on recommended displays for vital signs, electrocardiogram, and laboratory analyte measurements as outlined in PhUSE Computational Science Symposium (CSS) white papers as part of a standardization and code-sharing effort.

Examples of Discussed Topics
Whether to report p-values and confidence intervals
Handling of measures collected in reflex manner, repeated measures, unplanned measures, measurements post drug exposure
Defining baseline
Central versus local laboratories
Choices of lab reference limits
Units and transformations
ECG correction factors
Recommended Tables and Figures
• Allows for visual inspection of changes over time• Can visually assess the potential
impact of outliers on the central tendency summary statistic• Out of range values in red
• Easy to see treatment differences• Summary table compliments box
plot so numbers are available for textual summaries
Two pages per measuremento One for Max. baseline vs. Max.
post-baseline (shown on the left)o Another identical one for Min.
baseline vs. Min. post-baseline
• Scatter ploto Shows patient level informationoAllows quick browsing through a
large amount of information• Shift table
o Shows useful summary level statistics
• Treatment emergent high/low tableo Shows concise summary level
statistics oAllows for easy assessment of
treatment difference
Acknowledgements: Special acknowledgement to members of the PhUSE Computational Science Symposium Standard Scripts for Analysis and Programming Working Group, White Papers Project Team who have contributed to the white papers, and to those who have provided review comments.
• Only has mean and SD - Lacks additional useful summary statistics• Outliers not
displayed• Can be misleading
when data are non-normal
• Lack of information on patient level informationo Lack of magnitude of shift • Difficult to assess overall
treatment differenceo Very popular, however, users
tend to count and create grouped percentages manually for those shifting to high from low/normal (or low from normal/high).
