Fig. 3From: The clinical features of pulmonary artery involvement in Takayasu arteritis and its relationship with ischemic heart diseases and infectionSerious infection, respiratory infection, and nontuberculous mycobacteria (NTM) infection during the observation period. Kaplan-Meier graphs show the rate of developing serious infection, respiratory infection, and NTM infection in Takayasu arteritis (TAK) patients with or without pulmonary artery involvement (PAI) during the observation period. The y-axis represents the cumulative incidence of infection. Hazard ratio (HR) represents comparison of survival curves (PAI/without PAI) using log-rank test.
