Sensitivity to Selection Criteria Study Results: PRESERVE

- The demographic distribution of both cohorts is generally the same. - Patients meeting the alternate cohort definition generally enter the cohort at a younger age, have longer follow up, and have a higher median number of facts. This cohort also has a higher proportion of patients with a hypertension diagnosis compared to the base cohort. This indicates the eGFR requirement is likely pulling in sicker kids who require more care, resulting in more frequent and fact-dense encounters with the health system.
