Factors associated with vascular calcification in peritoneal dialysis patients: a meta-analysis.
Article in International urology and nephrology, 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
purposePeritoneal dialysis (PD) is a core renal replacement therapy for end-stage renal disease (ESRD), but PD patients face elevated cardiovascular risk, with vascular calcification (VC) severely impairing long-term prognosis. This meta-analysis aimed to synthesize factors associated with VC in PD patients to support early risk stratification and targeted clinical management.
methodsWe searched the Cochrane Library, Web of Science, PubMed, and Embase up to June 30, 2026, for English studies on factors associated with VC in PD patients. Study quality was assessed via the Newcastle-Ottawa Scale, and pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. The protocol was registered (CRD420251241785).
resultsTwenty-nine studies (3,696 PD patients) were included. Factors significantly associated with VC included: age (OR 1.09, 95% CI 1.07-1.11, P < 0.001), diabetes (OR 5.21, 95% CI 3.73-7.28, P < 0.001), hypertension (OR 5.29, 95% CI 1.70-16.48, P < 0.001), low vitamin D (OR 0.52, 95% CI 0.30-0.91, P = 0.02), low albumin (OR 0.93, 95% CI 0.90-0.97, P < 0.001), elevated alkaline phosphatase (OR 2.92, 95% CI 2.90-2.95, P < 0.001), HbA1c (OR 2.59, 95% CI 1.89-3.55, P < 0.001), dialysis duration (OR 1.04, 95% CI 1.01-1.07, P = 0.01), and lipid-lowering agent use (OR 2.26, 95% CI 1.31-3.91, P < 0.001), among others.
conclusionsMultiple clinical and biochemical factors are associated with VC in PD patients. These findings offer useful evidence for early identification of high-risk patients and tailored management, with further large-scale prospective studies needed for validation.
