EQscore

EQscore quantifies erythema in dermatological images by analyzing green light suppression differentials between affected and unaffected skin areas to provide objective measurements across Fitzpatrick skin types.

Key Features:

• Algorithmic Precision: Quantifies erythema by analyzing green light suppression differentials and reports measurements across Fitzpatrick skin types.
• Validation and Reliability: Validated against independent image sets including psoriasis, minimal erythema dose testing, and steroid-induced blanching, yielding an intra-class correlation coefficient (ICC) of 0.84 for the algorithm versus 0.67 for dermatologists.
• Correlation with Clinical Assessment: Correlated with evaluations by a panel of four dermatologists using a 4-point Likert scale across 164 reactions, producing a correlation coefficient of 0.85.

Scientific Applications:

• Clinical Trials: Provides objective outcome measures for erythematous conditions in clinical trials.
• Dermatological Diagnostics: Assists dermatologists in rating severity of skin conditions and monitoring therapeutic responses.
• Research Studies: Supports studies on skin pigmentation effects and treatment efficacy by providing reliable erythema quantification.

Methodology:

Computer-assisted image-processing algorithm that quantifies green light suppression differentials between affected and unaffected skin areas.
