Comparison of catheter outcomes according to dialysis modality and clinical factors in patients with femoral dialysis catheters.
Article in BMC nephrology, 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
backgroundAlthough femoral vein catheters are less preferred than internal jugular vein catheters, they are still actively used as an alternative. However, limited studies have assessed whether the patency of femoral vein catheters differs according to the initial dialysis modality. We compared and analyzed femoral vein catheter outcomes according to the initial dialysis modality and clinical factors.
methodsWe retrospectively analyzed medical records of 279 patients (a total of 318 cases) who underwent femoral vein catheterization for hemodialysis from January 2019 to August 2023. We divided the patients into two groups according to the initial dialysis modality (hemodialysis group [n = 182] and continuous renal replacement therapy group [n = 121]) and analyzed catheter survival.
resultsWe eventually included 303 cases of femoral vein catheterization for hemodialysis from 264 patients. Catheter survival did not differ significantly between the hemodialysis and continuous renal replacement therapy groups. Body mass index was associated with overall catheter survival. In the hemodialysis group, no significant factor was associated with catheter survival. However, in the continuous renal replacement therapy group, increased body mass index, age, and platelet counts were associated with low catheter survival.
conclusionFemoral dialysis catheter survival was not associated with the initial dialysis modality, and a high body mass index was associated with low survival rates of femoral dialysis catheters in patients who underwent continuous renal replacement therapy. CLINICAL TRIAL NUMBER: Not applicable.
