  1. Proteins significantly associated with mortality, poverty status, race, and sex were determined from linear regressions and indicated with an X in the columns. Proteins reported to be present in EVs in databases (ExoCarta and Vesiclepedia) are indicated with a “yes”. General functions of proteins are listed, not necessarily functions attributed to these proteins in EVs.
