Vitamin D Deficiency and Driveline Infections in Patients With Left Ventricular Assist Devices.
Article in Artificial organs, 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
backgroundDespite major advancements in the field of durable left ventricular assist devices (LVADs), driveline infection is a major source of morbidity and mortality. Risk factors have been proposed, but few are modifiable. We evaluated vitamin D deficiency as a potential modifiable risk factor for driveline infection. METHODS AND
resultsThis single-center, retrospective study included 134 LVAD recipients between 2010 and 2022. Patients were divided into two groups based on their pre-implant vitamin D levels: the vitamin D sufficient group (≥ 30 ng/mL) and the vitamin D deficient group (< 30 ng/mL). The Kaplan-Meier method estimated 18-month freedom from driveline infection. The Cox proportional hazards model estimated the effect of vitamin D deficiency on driveline infections. Kaplan-Meier estimates for infection-free survival were significantly higher in the sufficient group (90.5% vs. 69.6%, p = 0.014). Vitamin D deficiency (HR: 3.644, 95% CI: 1.271-10.448, p = 0.016) and obesity (HR: 3.190, 95% CI: 1.464-7.400, p = 0.004) were found to be independent risk factors for driveline infection.
conclusionOur findings support vitamin D deficiency as a potential modifiable risk factor for driveline infection. Obesity was also noted as a significant risk factor for infection. Further research is warranted to establish causality and assess the impact of vitamin D repletion on infection rates.
