Figure 1.

Study outline and cohort selection. Period is defined as a segment of time during which a participant was uniquely on either home dialysis or facility-based HD (minimum of 30 days). Some participants transitioned in both directions multiple times over the course of the study and thus were at risk of transition in either direction more than once. This figure demonstrates discrete periods and not the number of participants. Abbreviations: HD, facility-based hemodialysis; ITSA, interrupted time series analysis.
