(a) Unsummarized probabilistic graphical model of the emergence of MCCs. (b) The summarized probabilistic graphical model using the EAGL summarization algorithm at a 20% summarization rate. Each node is a binary (0,1) variable representing the status (presence or absence) of a chronic condition in a particular year, that is, TBIY1 denotes the status of TBI at year-1 (base year), and BaPaY5 denotes the status of BaPa in year-5. BaPa, back pain. In the figure, BaPa: back pain; TBI: traumatic brain injury, PTSD: posttraumatic stress disorder and SuAb: substance abuse, MCC: multiple chronic condition, EAGL: eigen analysis of graph Laplacian.
