Long-Term Durability of Tunneled Hemodialysis Catheters: Outcomes from a Single Institution 22-Year Experience.
Article in Cardiovascular and interventional radiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeTo describe long-term physical durability of tunneled hemodialysis catheters, highlighted in the 2019 Kidney Disease Outcomes Quality Initiative (KDOQI) guidelines as a specific area for future research. MATERIALS AND
methodsTunneled hemodialysis catheters with known outcomes and dwell times > 1 year were entered into this retrospective study. Data includes demographics, complications, catheter type, dwell time, reason for removal, access site, and placement via exchange or de novo. Catheter durability < 1 year dwell was analyzed as a secondary aim.
results272 catheters in 229 patients were included. Dwell times ranged from 366 to 3,802 days (median 504), totaling 162,439 catheter days. 17 (6%) catheters > 1 year dwell had broken external components. For these, dwell times until breaking ranged from 377 to 1,436 days (median 489), totaling 10,434 catheter days. 5 had a broken hub, 11 had a broken clamp, and 1 had broken hub and clamp. 12 were Ash Split Cath (n = 240) and 5 were Arrow-Clark VectorFlow (n = 32). In the durability < 1 year sub-analysis, 6,515 catheters with dwell times < 1 year in 3,693 patients were included, totaling 425,018 catheter days. 48 were damaged, with 24 broken hubs, 17 broken clamps, and 7 holes. Median time to breakage was 110 days. 38 were Ash Split Cath (n = 5,636) and 10 Arrow-Clark VectorFlow (n = 812). In both analyses, breakage was limited to hubs, clamps, and extensions.
conclusionsTunneled hemodialysis catheters are exceptionally durable, rarely requiring removal for hub-related issues after one year. Breakdown was not observed as a long-term durability issue. Further, broken external components can be replaced using external repair kits. LEVEL OF EVIDENCE: Level 2b, Retrospective Study.
