Methodological stages for classification. The classification of clinical trial records has 5 stages. The 4 initial stages allow for deriving pathways from the clinical trial record to candidate GBD categories: annotation of text from the trial record with UMLS concepts by using MetaMap, projection of UMLS concepts to ICD10 codes with IntraMap, projection of ICD10 codes to candidate GBD categories, and expert-based enrichment when automatic pathways are not possible. The fifth stage allows for deriving the GBD classification of the trial based on prioritization rules over the pathways found
