Substudy Dataset of type 2 Diabetes in Macular Telangiectasia Type 2
The AI-READI project seeks to create and share a flagship ethically-sourced dataset of type 2 diabetes.
Overview of the study
The Artificial Intelligence Ready and Exploratory Atlas for Diabetes Insights (AI-READI) project seeks to create a flagship ethically-sourced dataset to enable future generations of artificial intelligence/machine learning (AI/ML) research to provide critical insights into type 2 diabetes mellitus (T2DM), including salutogenic pathways to return to health. The ability to understand and affect the course of complex, multi-organ diseases such as T2DM has been limited by a lack of well-designed, high quality, large, and inclusive multimodal datasets. The AI-READI team of investigators will aim to collect a cross-sectional dataset of 4,000 people and longitudinal data from 10% of the study cohort across the US. The study cohort will be balanced for self-reported race/ethnicity, gender, and diabetes disease stage. Data collection will be specifically designed to permit downstream pseudo-time manifold analysis, an approach used to predict disease trajectories by collecting and learning from complex, multimodal data from participants with differing disease severity (normal to insulin-dependent T2DM). The long-term objective for this project is to develop a foundational dataset in T2DM, agnostic to existing classification criteria or biases, which can be used to reconstruct a temporal atlas of T2DM development and reversal towards health (i.e., salutogenesis). Data will be optimized for downstream AI/ML research and made publicly available.
Description of the dataset
This dataset contains data from 2280 participants that was collected between July 19, 2023 and May 01, 2025. Data from multiple modalities are included. A full list is provided in the Data Standards section below. The data in this dataset contain no protected health information (PHI). Information related to the sex and race/ethnicity of the participants as well as medication used has also been removed.
The dataset contains 356,343 files and is around 3.81 TB in size.
A detailed description of the dataset is available in the AI-READI documentation for v3.0.0 of the dataset at docs.aireadi.org.
Protocol
The protocol followed for collecting the data can be found in the AI-READI documentation for v3.0.0 of the dataset at docs.aireadi.org.
Dataset access/restrictions
Accessing the dataset requires several steps, including:
- Login in through a verified ID system
- Agreeing to use the data only for type 2 diabetes related research.
- Agreeing to the license terms which set certain restrictions and obligations for data usage (see
Licensesection below).
Data standards followed
This dataset is organized following the Clinical Dataset Structure (CDS) v0.1.1. We refer to the CDS documentation for more details. Briefly, data is organized at the root level into one directory per datatype (c.f. Table below). Within each datatype folder, there is one folder per modality. Within each modality folder, there is one folder per device used to collect that modality. Within each device folder, there is one folder per participant. Each datatype, modality, and device folder is named using a name that best defines it. Each participant folder is named after the participant's ID number used in the study. For each datatype, the data files follow the standards listed in the Table below. More details are available in the dataset_structure_description.json metadata file included in this dataset.
