Impact of type of vascular access on clinical outcomes in peritoneal dialysis patients transitioning to haemodialysis: an ANZDATA study.
Article in Clinical kidney journal, 2025. 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
Background: Type of vascular access used for haemodialysis is associated with long-term outcomes. However, the effect of access on haemodialysis transfer for peritoneal dialysis (PD) patients has not been fully explored. Methods: A retrospective cohort study was performed in incident adult PD patients from the Australian and New Zealand Dialysis and Transplant (ANZDATA) Registry who transferred to haemodialysis between 2004 and 2022. Associations between vascular access on transfer [central venous catheter (CVC) or arterio-venous access (AVA)] and clinical outcomes (all-cause mortality, cause-specific mortality, kidney transplantation and return to PD) were compared using Cox proportional hazards analysis and competing risk models. Results: Of 6824 patients, 65% used a CVC on transfer and 35% an AVA. Variability of access type at transfer between centres was high (range 13%-98% for CVC). AVA transfer was associated with a longer PD vintage (1.6 versus 1.2 years, Conclusions: Patients who transferred with an AVA, compared with a CVC, showed better survival and kidney transplantation rates, but were less likely to return to PD.
