The dataset is a collection of Vivli member study listings and related access information, covering studies available through the Vivli Platform as well as guidance for enquiring about studies not yet listed. It contains study-level availability details, instructions for submitting enquiries or data access requests, account requirements for platform use, and notes on member-specific submission processes and response discretion. Its purpose is to support researchers and other users in identifying relevant clinical study data, obtaining additional study information, and requesting access to shared datasets, while reflecting member policies such as limits on sharing studies before primary completion.
