This not-yet-peer-reviewed study 
pioneers using artificial intelligence to analyze and categorize an extensive array of CDR research. The team hand-labelled 5,339 documents, leveraging machine learning classifiers to sift through and identify a remarkable total of 28,976 CDR studies published from 1990 to 2022. This figure surpasses previous estimates by 2-3 times, underscoring the field’s rapid growth and increasing complexity.
