Reproduced with permission from Munson et al [21]. Association diagram showing the clinical milieu in which CN (pink node in center of square) often exists. Each node represents an ICD-9 code, with the size of the node proportional to its frequency in the overall dataset, and node colors representing high-level clinical categories (see legend). Edges between nodes represent highly significant associations. Arrowheads show temporality with preceding nodes pointing to subsequent nodes. This figure was made using the following criteria: Association p-value < 1.0 × 10-176; association odds ratio > 200; temporal p-value < 1.0 x 10-6. The two red nodes directly pointing to Charcot foot are related to type 2 diabetes (ICD-9 codes 250.60 and 250.90)
