– Age-standardized death rates for pulmonary hypertension as a contributing cause of death and trend lines among individuals of all ages, by race/ethnicity: 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 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). ^aRates are per 100,000 population and are age standardized to the 2000 US standard population (eight age groups); ^ball race/ethnicity trend lines are parallel to the referent group of NHW, P < .05. There are no statistically significant coincident trend lines to the referent group of NHW. See Table 6 for additional data. NHAIAN = non-Hispanic American Indian/Alaska native; NHAPI = non-Hispanic Asian/Pacific Islander; NHB = non-Hispanic black; NHW = non-Hispanic white.
