Use of 4% tetrasodium EDTA (KiteLock™) to prevent central venous catheter-related bloodstream infections in pediatric hemodialysis patients.

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
backgroundCentral venous catheter (CVC)-related bloodstream infections (CRBSI) are common in children receiving hemodialysis and cause significant morbidity and healthcare costs. Unlike standard locking solutions, 4% tetrasodium EDTA (KiteLock™) has antimicrobial and antibiofilm properties. We aimed to study the safety and efficacy of 4% tetrasodium EDTA CVC locking in pediatric hemodialysis.
methodsSingle-center, before-and-after quality improvement study. We included all chronic hemodialysis patients (6 months-18 years) from 2016-2022 (before) to 2022-2024 (after). The standard CVC locking solution was changed from heparin (1000 units/mL) to 4% tetrasodium EDTA. We compared unit-level incidence of CRBSI, CVC replacement procedures (exchange or removal and reinsertion), laboratory results, alteplase use, and adverse events before and after 4% tetrasodium EDTA implementation.
resultsWe included 22 pediatric chronic hemodialysis patients (median age 13.5 years, 50% female). CRBSI incidence was 0.89 infections per 1000 catheter-days (25,769 total catheter-days) before and 0.18 per 1000 catheter-days (5426 total catheter-days) after 4% tetrasodium EDTA (IRR 0.21, 95%CI 0.03-1.52). CVC replacement procedure incidence was 1.99 procedures per 1000 catheter-days (4027 total catheter-days) before and 1.29 per 1000 catheter-days (5426 total catheter-days) after 4% tetrasodium EDTA (IRR 0.65, 95%CI 0.24-1.79). There were no significant differences in hemodialysis treatment parameters, alteplase use (12% of treatments before vs. 18% after), or access complications (12% of treatments before vs. 15% after).
conclusionsCVC locking with 4% tetrasodium EDTA was associated with sustained reductions in CRBSI and CVC replacement procedure incidence. Incorporation of 4% tetrasodium EDTA locking into standardized CVC care bundles may prolong vascular access survival.
