Clusters associated with osteoarthrosis. Four clusters containing disease trajectories associated with osteoarthrosis (ICD-9 code 715), extracted by the DTW clustering algorithm on the female sub-population. In each cluster, bladder cancer represented more than 20% of the total diagnoses. The nodes are drawn at a size relative to the frequency of appearance of the disease or group of diseases (a minimum node size corresponding to a frequency of 5% has been arbitrarily considered). Shorter and longer trajectories formed by connected nodes are contained in each cluster. Cyclic arrows indicate additional distinct diagnoses belonging to the same group of diseases (repetitions of the same disease are not permitted in a single trajectory).
