From: Epidemiology and comorbidities in idiopathic pulmonary fibrosis: a nationwide cohort study
Annual prevalence and incidence rates of idiopathic pulmonary fibrosis from 2011 to 2019 in South Korea. The red solid line shows the incidence/100,000 person-years (left y-axis) and the blue dotted line shows the prevalence/100,000 people (right y-axis). Both prevalence and incidence rates showed statistically significant annual increases (p < 0.001 by Poisson regression analysis)
