Referencing data found in the IPD

Clarivate takes great care to provide complete citations for all sources used in compiling our data so that our clients may in turn cite these sources appropriately. All Clarivate databases cite surveys published by the National Center for Health Statistics (NCHS) in Hyattsville, Maryland. In addition, the Incidence & Prevalence Database (IPD) provides Article Reviews, IPD Summaries, and Global Incidence & Prevalence Reports based primarily on publications from peer-reviewed medical literature.
