Silicone Rubber Catheters Modified by Poly(N-vinylpyrrolidone) Graft Promoted by Gamma Rays.
Article in Polymers, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
The functionalization of polymeric matrices through graft polymerization offers multiple advantages by introducing new properties through the incorporation of functional chemical groups on the surface. These modifications can change the chemical properties of the matrix, such as hydrophilicity and chemical reactivity, and enable new chemical interactions with other molecules that the matrix alone could not achieve. This expands the applicability of the material in various fields, particularly in medicine, where these functionalized matrices can be employed as drug delivery systems. In this work, poly(N-vinylpyrrolidone) was incorporated through a graft polymerization of N-vinylpyrrolidone on silicone rubber catheters using gamma radiation to promote the polymerization reaction on the matrix. The graft degree of poly(N-vinylpyrrolidone) on the SR matrix was studied based on the absorbed dose and monomer concentration. Additionally, the new materials were characterized using TGA, wettability kinetics, ATR-FTIR, and Raman spectroscopy, as well as a drug loading evaluation.
