Datasets Dashboard

Introduction

This dashboard provides key metrics and interactive summaries for datasets available in neurodegenerative disease research. [@timmers2024] The dashboard serves as a quick-reference hub for data availability, quality metrics, and resource connections across genomics, transcriptomics, proteomics, imaging, and clinical domains.
