Tunneled Hemodialysis Catheters: Six Current Questions.
Review in Interventional radiology (Higashimatsuyama-shi (Japan), 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
This review examines six key questions about tunneled hemodialysis catheters: material selection, tip design, insertion site, optimal tip positioning, fibrin sheath management, and infection prevention. Most modern catheters use polyurethane-polycarbonate copolymers that resist material failure. Symmetric-tip designs reduce dysfunction rates compared to other designs. While the right internal jugular vein is preferred, patient-specific factors should guide insertion site selection. Left-sided catheters benefit from right atrial tip positioning, whereas right-sided catheter tip location is less critical. Fibrin sheaths commonly cause catheter dysfunction, and multiple treatment methods are available, with no clear single best approach. Infection risk is multifactorial, with evidence supporting targeted preventive measures. While catheter materials and designs continue to evolve, individualized management remains essential.
