Sample Outputs and Deliverables

This page shows the concrete outputs that sponsors, CROs, and investigators receive from each atopic dermatitis severity assessment. The AI generates structured ASCORAD reports immediately after image submission — no central reader, no delays.

Per-visit assessment report

Each image submission generates a complete ASCORAD report, accessible within seconds:

What the report contains

Output	Detail
Objective SCORAD	0–72 computed from BSA + intensity signs
Total SCORAD	0–103 including patient-reported pruritus and sleep disturbance
BSA percentage	Per-area and global affected body surface area
Per-sign scores	Erythema, oedema, oozing, excoriations, lichenification, dryness (each 0–3)
Segmentation masks	Pixel-level eczema area masks per body region
Image quality (DIQA)	Quality score per image; failed images flagged for recapture
Severity classification	Mild (<25) / Moderate (25–50) / Severe (>50)
Timestamp	UTC timestamp of capture and AI processing

AI visual outputs

BSA segmentation masks

For each body area, the AI generates a pixel-level segmentation mask showing exactly which skin areas are classified as affected by eczema.

Original photograph

Input: body area photograph

Segmentation mask

Output: affected area at pixel level

Overlay on original

Combined: segmentation overlaid on photograph

Per-sign intensity visualisations

Each of the six SCORAD intensity signs is scored and visualised independently:

Erythema intensity map

Erythema (redness) heat map

Excoriation detection

Scratch mark pattern recognition

Lichenification detection

Thickened skin texture classification

Anonymization

All photographs are processed with automatic face anonymization, ensuring patient privacy for stored and exported images.

Before anonymization

Original capture

After anonymization

Irreversible face blurring applied

Longitudinal severity tracking

The platform tracks SCORAD evolution across visits from screening to end of study:

Visit 1 (T0) report

Baseline: SCORAD with segmentation and sign scores

Visit 2 (T1) report

Follow-up: SCORAD change from baseline

What longitudinal tracking delivers

• SCORAD trajectory: Score at every visit from screening to end of study
• Absolute and percentage change from baseline at each visit
• Per-sign trend: Which intensity signs are driving improvement or worsening
• BSA evolution: How the extent of affected area changes over time
• Visual chart: Graphical severity curve across all timepoints

Data export for EDC integration

All assessment outputs are structured for export to the sponsor's EDC system:

Field	Description
Patient ID	Pseudonymised study identifier
Visit ID	Visit number or scheduled timepoint
Timestamp	UTC timestamp of capture and processing
Total BSA (%)	Affected body surface area
Per-sign scores	Erythema, oedema, oozing, excoriations, lichenification, dryness (each 0–3)
Objective SCORAD	Computed objective component (0–72)
Total SCORAD	Including patient-reported symptoms (0–103)
Severity classification	Mild / Moderate / Severe

Data is transferred automatically via RESTful API or CSV/Excel export. Legit.Health provides IQ/OQ documentation and data mapping specifications.

Reliability of the scores

The ASCORAD system was validated in a peer-reviewed pilot study (Medela et al., JID Innovations, 2022). Like all Legit.Health scoring systems, ASCORAD is perfectly reproducible: the identical image always produces the identical score, at every site, without calibration drift.
