Note. NHDS = National Hospital Discharge Survey.
aPrevalence rates were calculated as the number of pregnant women with the condition (obtained from the NHDS) per 100 000 live births (obtained from National Center for Health Statistics natality files).
bCase-fatality rates were calculated as the number of deaths attributable to that condition (obtained from the Pregnancy Mortality Surveillance System) per 100 000 women with that condition (obtained from the NHDS).
