+
+## Dataset Summary
+
+FairGenMed is the first dataset for studying **fairness in medical generative models**. It provides detailed quantitative clinical measurements alongside demographic annotations to investigate the semantic correlation between text prompts and anatomical regions across demographic subgroups. The dataset supports both generative model evaluation and downstream classification tasks for glaucoma detection.
+
+This dataset accompanies the **FairDiffusion** framework — an equity-aware latent diffusion model that enhances fairness in medical image generation via Fair Bayesian Perturbation — published in *Science Advances* (2025).

+
+### Data Fields
+
+Each subject includes one SLO fundus image and one `.npz` file. The NPZ files contain:
+
+| Field           | Description |
+|-----------------|-------------|
+| `glaucoma`      | Disease label: `0` = non-glaucoma, `1` = glaucoma |
+| `oct_bscans`    | OCT B-scan images |
+| `race`          | `0` = Asian, `1` = Black, `2` = White |
+| `male`          | `0` = Female, `1` = Male |
+| `hispanic`      | `0` = Non-Hispanic, `1` = Hispanic |
+| `maritalstatus` | `0` = Married/Partnered, `1` = Single, `2` = Divorced, `3` = Widowed, `4` = Legally Separated, `-1` = Unknown |
+| `language`      | `0` = English, `1` = Spanish, `2` = Other |
+
+### Clinical Metadata
+
+All clinical measurements for the 10,000 samples are provided in `data_summary.csv`:
+
+| Column        | Description |
+|---------------|-------------|
+| `cdr_status`  | Cup-disc ratio status |
+| `md_severity` | Severity of vision loss |
+| `se_status`   | Spherical equivalent status |
+
+### Demographics
+
+6 demographic attributes are annotated per subject: age, gender, race, ethnicity, preferred language, and marital status.
+
+## Uses
+
+### Direct Use
+
+- Fairness evaluation of medical generative models (text-to-image diffusion)
+- Glaucoma detection with demographic fairness analysis
+- Studying semantic correlations between text prompts and anatomy across subgroups
+
+### Out-of-Scope Use
+
+Clinical decisions, patient care, or any commercial application. This dataset shall not be used for clinical decisions at any time.
+
+## Associated Method: FairDiffusion
+
+FairDiffusion is an equity-aware latent diffusion model built on Stable Diffusion 2.1, trained with **Fair Bayesian Perturbation** to reduce demographic bias in generated medical images. It is evaluated on FairGenMed (ophthalmology), HAM10000 (dermatology), and CheXpert (chest radiology).
