Biomarker Screening & Diagnostic Model
Project Question
A translational research group wanted to identify candidate biomarkers for early disease detection and build a diagnostic scorecard with validation metrics.
Analysis Approach
Performed differential expression analysis, feature selection, and machine-learning model training with cross-validation. Evaluated performance using ROC, AUC, DCA, and calibration curves.
Input Data
- Clinical cohort expression data
- Phenotype labels
- Validation cohort (if available)
Deliverables
- Biomarker ranking table
- ROC / AUC / DCA plots
- Calibration curve
- Diagnostic scorecard
- Model performance report
Representative ROC curve generated from mock data for layout demonstration.
This output represents the analytical approach and visualization style. Actual project results depend on input data quality, sample size, and validation strategy.
