The Changing Landscape of Peritoneal Dialysis in America: A Facility-Level Analysis of Growth.
Article in Kidney medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Rationale & Objective: Peritoneal dialysis (PD) use has expanded nationwide, yet it is unclear whether this growth reflects more facilities initiating PD programs, expansion of existing programs, or both. We sought to describe national trends in PD program adoption and program size and to assess whether these patterns differed across facility and geographic characteristics. Study Design: Retrospective serial cross-sectional study. Setting & Participants: All Medicare-certified dialysis facilities in the United States from 2010-2021. Exposure: Calendar year. Outcomes: (1) Whether a facility treated ≥1 PD patient; (2) PD census among facilities with active PD programs. Analytical Approach: We applied mixed-effects logistic and negative binomial models with random facility effects to estimate changes in PD program presence and the mean census over time. Models were adjusted for region, organizational size, profit status, and urbanicity, and included interaction terms to test for heterogeneity in temporal trends. Results: The number of US dialysis facilities with active PD programs increased from 38.4%-44.6% between 2010 and 2021, and among those programs, the mean PD census rose from 14.7-18.2. Relative to 2010, facilities in 2021 had higher odds of providing PD (OR, 1.61; 95% CI, 1.35-1.92), and active programs treated substantially more patients (incidence rate ratio, 1.50; 95% CI, 1.45-1.56). Nonprofit and small dialysis organizations showed the greatest likelihood of initiating PD programs, whereas for-profit and large organizations demonstrated stronger census growth. Regional differences were observed, with the West showing the largest increases in program size. Limitations: Facility-level data prevent examination of patient-level determinants; annual snapshots may miss within-year variation. Conclusions: From 2010-2021, PD growth reflected both expansion of existing programs and increased program adoption, with substantial differences based on organizational structure. Tailored policy strategies may be needed to support sustained, equitable growth in PD capacity across facility types.
