Preemptive Vascular Access Placement and Mortality Risk in Hemodialysis Patients: A Real-World Single-Center Study.
Article in Hemodialysis international. International Symposium on Home Hemodialysis, 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
backgroundThe optimal timing for vascular access creation in hemodialysis (HD) patients is critical for improving patient outcomes. This study aimed to investigate the association between preemptive vascular access placement and all-cause mortality in HD patients.
methodsA retrospective cohort of 489 adult HD patients from 2009 to 2022 was analyzed. Patients were categorized into preemptive and non-preemptive vascular access groups. Inverse probability of treatment weighting (IPTW) was used to balance baseline characteristics, and survival analyses were performed using Kaplan-Meier curves, log-rank tests, and Cox proportional hazards models.
resultsPreemptive vascular access was found in 20.7% (101/489) of patients. After IPTW adjustment, the preemptive group had lower mortality (8.9% vs. 18.8%, p < 0.001) and a 65% reduction in all-cause mortality risk (adjusted HR = 0.35, 95% CI 0.15-0.80). Elderly patients (≥ 60 years) showed greater survival benefits (p for interaction < 0.05).
conclusionsPreemptive vascular access placement significantly improves survival in HD patients, particularly in older adults. However, excessively early placement (> 6 months) offers no additional prognostic advantage.
