Cholesterol Functionalized Nanoparticles Are Effective against Helicobacter pylori, the Gastric Bug: A Proof-of-Concept Study.
Article in Advanced healthcare materials, 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
Helicobacter pylori chronic infection is the highest risk factor for the development of gastric cancer, being this Gram-negative bacterium classified as carcinogenic. The mounting resistance of H. pylori to antibiotics calls for innovative therapeutic strategies. Here, the proof-of-concept studies that support the development of a "trojan horse" therapeutic strategy based on cholesterol-grafted nanoparticles (Chol-NP) to counteract H. pylori infection are depicted. The bacterium ability to specifically recognize and bind to surface grafted cholesterol is demonstrated by its adhesion to cholesterol(Chol)-functionalized self-assembled monolayers (SAMs) on gold substrates (2D Chol-SAMs) in a concentration dependent manner, with optimal Chol-SAMs prepared with 25% Chol-polyethylene glycol (PEG)-thiol in solution (75% tetra(ethylene glycol)-thiol). These results further show that cholesterol functionalized gold nanoparticles (3D Chol-SAMs, Chol-NP) eradicate H. pylori at a minimum bactericidal concentration of 125 µg mL
