Clinical trial stop reasons
This model is a fine-tuned version of bert-base-uncased on the task of classification of why a clinical trial has stopped early.
The dataset containing 3,747 manually curated reasons used for fine-tuning is available in the Hub.
More details on the model training are available in the GitHub project (link) and in the associated publication (TBC).
