Demographics

NIH mandates that all studies include an appropriately diverse study population. If you are studying healthy subjects or if there is no gender/race/ethnic predilection for the disease, please list normal population demographics(gender or race/ethnic). Categories of "other" and "two or more" are not required by NIH; they are included here if they were present in the source data.
