Computational Diagnostics

Visualization Goal: Identify factors that cause relapse in

patients

Relapse insight can be gained by –

Global overview of medical condition of all patients in the

dataset

Ability to identify worst medical condition in patients

Comparing patient medical condition at diagnostic

variable(s) level

Ability to identify and compare patient groups that share

similar medical

condition across multiple variablesDr. Susanane Raggs Dr. Katy Börner Ketan Mane Julie Haydon Jada Pane

Computational Diagnostics - Dataset Details

Diagnostic data variables from medical records for Acute Lymphoblastic Leukemia (ALL) patients are categorized into a. Outcome Patient Variables: relapse, relapse site, alive/death status, and LDKA.

b. Biology Patient Variables: immunophenotype, genetic condition, WBC, Hgb, platelets, and CNS. c. Host Patient Variables: diagnostic age (ageDx), gender, and race.

d. Treatment Patient Variables: BM 7 and BM 14.

e. Social Factors Patient Variables: MFI-class, education level, %single family members, and % family employment.

All data was provided by Dr. Susanne Raggs, Julie Haydon and Jada Pane.

Matrix Visualization – Phenotype View

Data is shown independent of other variables.

Color codes help to provide a quick insight into patient medical

condition.

Matrix Visualization – Prognosis View

Color codes indicate event free survival in percent (%EFS).

All variable values are dependent on other variable values.

Matrix Visualization – Combined View

Facilitates selection of phenotype/prognosis view for individual

diagnostic variables.

Parallel Coordinates Visualization

Uses one axis for each data variable.

For each patient, all data values on different parallel axis are connected.

All patient graphs are shown here.

Single or multiple patients can be selected and studied in detail.


Tool-tip display to show diagnostic values of selected

patient.

Parallel Coordinates Visualization – User Interactions

Display axes-labels to mark different regions/values along

axes

Numerical landmarks along axes showing values for

quantitative variables.

Category labels used along axes show values for nominal

variables.


Display zones to show severity values for different variables

Triangular zones indicate variables with quantitative values.

Rectangular zones are used for variables with nominal values.


Axis selection to study global variations in patient values

Single axis can be selected to study the trend in patient values.

Red-to-green gradient used to indicate values along the

selected axis.

[Red = High value, Green = Low value]


A subset of patents can be selected and examined as a

group.


Simultaneous display of patient groups to study differences.

Patient Group 1

Patient Group 2

Patient Group 1 & 2


Multiple Coordinated Views

Patient can be selected and color coded in matrix view.

Corresponding patient lines are highlighted in parallel

coordinate view.
