Mobilization of a peritoneal dialysis catheter using an extra-corporeal magnet: preliminary experimental phase study.
Article in International urology and nephrology, 2021. 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
purposeTo evaluate in an experimental model, the mobility of a novel peritoneal dialysis catheter with a metallic tip (Mag-Cath) using an extra-corporeal magnet. MATERIALS AND
methodsThe Mag-Cath was installed in a porcine model under general anesthesia using laparoscopic access. A senior urologist, a urology resident, and a 3rd-year medical student were assigned to complete 2 tasks guided by fluoroscopy: (1) Move the catheter tip from the right flank to the pelvis and (2) move the catheter tip from the pelvis to the left flank. Accomplishment and time to complete the tasks were recorded. Participants were asked independently to grade the difficulty of the tasks using an analog scale from 1 (extremely easy) to 10 (extremely difficult).
resultsAll participants completed the tasks. The difficulty of the tasks was graded equal to 1 by the senior urologist and urology resident and equal to 3 by the medical student. The time to move the Mag-Cath from the right flank to the target was 14, 10, and 55 s for the senior urologist, urology resident, and medical student, respectively. The time to move the Mag-Cath from the target to the left flank was 17, 18, and 43 s for the senior urologist, urology resident, and medical student, respectively.
conclusionIn this preliminary analysis, the use of an extra-corporeal magnet to move the Mag-Cath was feasible, with a low grade of difficulty, and individuals with different levels of expertise could perform it. Further studies in human subjects are needed to evaluate the clinical applicability of the Mag-Cath properly.
