Prospective Evaluation of Remote Software Based Surveillance Supplementing Clinical Monitoring for Haemodialysis Vascular Access.
Article in Nephron, 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
backgroundEfficient arteriovenous vascular access (VA) surveillance is vital for early identification of dysfunctional access, allowing timely intervention to prevent thrombosis. This study compares the efficacy of adding remote software surveillance to standard clinical care across our units.
methodsWe conducted a 12-month prospective study on maintenance haemodialysis (HD) patients using Vasc-Alert software technology to assist clinical decision-making in 2 satellite HD units (group 1) and standard care in the remaining 3 HD units (group 2). Patients with Vasc-Alert-derived high Access Risk Score (ARS) (≥7) underwent clinical assessment and were referred for fistulogram based on relevant Kidney Disease Outcome Quality Initiative (KDOQI) criteria. Data on referrals for fistulogram, subsequent VA events, access abandonment, and complication-free days-extended (CFD-extended) were collected. VA survival analysis of post-intervention primary patency rate at 3 and 6 months was conducted.
resultsThere were 23 (28.1%) pre-emptive correction of stenosis and 6 (7.3%) thrombosis episodes in group 1, compared to 40 (19.5%) and 21 (10.2%) in group 2 (p value 0.155, 0.587), respectively). Among the thrombotic episodes, 83% of cases in group 1 had been detected during surveillance and referred for diagnostic fistulogram ± angioplasty but developed thrombosis while awaiting elective intervention compared to 19% in group 2 (p = 0.004). Median time from fistulogram request to thrombosed VA was 26 days (interquartile range: 21-42 days). Group 1 exhibited better post-intervention primary patency rates and longer CFD compared to group 2 (p value <0.001, 0.002, respectively).
conclusionIncorporating Vasc-Alert technology into VA clinical surveillance pathway was associated with improved early detection of high-risk VA, higher primary patency rates, and longer CFD-extended compared to standard of care. Improving elective interventional radiology capacity for timely intervention (<3 weeks from referral) is crucial to materialise the benefits of enhanced surveillance in preventing acute thrombosis.
