Phases of Follow-up in the PARIS Cohort. The active follow-up phase consists of 3 years of annual ambulatory follow-up visits for questionnaires and biospecimen collection and up to 4 years from enrollment for capture of hospitalization and AKI events among all participants, and an additional year of follow-up among those who are hospitalized. The subsequent passive follow-up phase allows for ongoing evaluation of long-term outcomes for the duration that the participant receives medical care within the Johns Hopkins Health System.
