Relationship between SBDH terms in reduced-dimensional (12,723) vector space model. a Heatmap of correlations between terms, where red represent high correlation and blue represents low correlation. b List of clusters with the highest intra-cluster correlations, depicting terms that are explicitly or conceptually synonymous as well as terms that share stems. c List of terms in clusters that account for 20% of the variability in the entire patient population
