Expected Variables Present Study Results II: PRESERVE

- Uiowa has an anomalously low proportion of patients with census tract information, which is expected due to known challenges at the institution - There are many anomalous institutions related to ABPM data, demonstrating relative heterogeneity and differences in site practice when coding for or administering this procedure - There are also several anomalous institutions related to antihypertensive exposure prior to cohort entry, which will require further investigation to determine why the population at these sites are exposed earlier than others.
