Figure. Disease Trajectory Network of the Combined International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10) and Proxy Groups for Hidradenitis Suppurativa (HS).

The temporal associations of diseases experienced by patients with HS are shown. All diseases that are part of the trajectory network are represented as orbs with arrows connecting them representing the temporal manifestation. All trajectories (3 diseases linked left to right through arrows) include a minimum 119 patients with HS. This corresponds to a minimum of 0.8% of the total HS population. Increased arrow width indicates a higher number of patients following the trajectory.
