Dataset Card: FairFedMed

Dataset Summary

FairFedMed is the first federated learning (FL) benchmark dataset for medical imaging with demographic annotations, designed to study group fairness across institutions in a federated setting. It comprises two subsets spanning ophthalmology and chest radiology, enabling research on fairness-aware federated learning under realistic cross-institutional data heterogeneity.

This dataset was introduced in the IEEE Transactions on Medical Imaging 2025 paper: FairFedMed: Benchmarking Group Fairness in Federated Medical Imaging with FairLoRA.

Subsets

FairFedMed-Oph (Ophthalmology)

Field	Value
Task	Glaucoma detection (binary classification)
Modalities	2D SLO fundus images, 3D OCT B-scans
Scale	15,165 patients
Demographics	Age, gender, race, ethnicity, preferred language, marital status (6 attributes)
FL Setup	Multi-site federated (3 sites)

FairFedMed-Chest (Chest Radiology)

Field	Value
Task	Chest pathology classification
Sources	CheXpert + MIMIC-CXR
Demographics	Age, gender, race (3 attributes)
FL Setup	2 clients simulating cross-institutional FL

Uses

Direct Use

Research on group fairness in federated medical image classification, including studies of demographic disparity across institutions and evaluation of fairness-aware FL methods.

Out-of-Scope Use

Clinical diagnosis, commercial applications. Note that FairFedMed-Chest inherits the usage restrictions of CheXpert and MIMIC-CXR — consult those datasets' licenses before use.

Evaluation

Metric	Description
AUC	Area Under ROC Curve
ESAUC	Equalized Selection AUC
EOD	Equalized Odds Difference
SPD	Statistical Parity Difference
Group AUC	Per-demographic-group AUC

Associated Method: FairLoRA

The paper introduces FairLoRA, a fairness-aware FL framework using SVD-based low-rank adaptation. It customizes singular values per demographic group while sharing singular vectors across clients for communication efficiency.

Supported backbones: ViT-B/16, ResNet-50.
