– Age-standardized death rates for pulmonary hypertension as a contributing cause of death and trend lines among individuals of all ages, by sex: United States, 2001-2010. The National Vital Statistics System was used to ascertain deaths due to pulmonary hypertension, which were considered those with decedents having International Classification of Diseases, 10th Revision (ICD-10) codes I27.0, I27.2, I27.8, or I27.9 reported as any contributing cause of death (ie, any of the possible 20 conditions, including the underlying cause of death). All trend lines are compared with the referent group, men; P < .05. Both parallelism and coincident comparison of trend lines were rejected. Rates are per 100,000 population and are age standardized to the 2000 US standard population (eight age groups). See Table 5 for additional data.
