Analyses with chi square tests and t-tests found no stastically significant differences between patients with potentially low-value vs appropriate PPI use by age, gender, race, ethnicity, and zip code derived household income.
PPI = Proton Pump Inhibitor; SD = Standard Deviation; AI/AN = American Indian/Alaska Native
