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
Medical-grade polyethylene (PE) surfaces are highly susceptible to bacterial colonization and biofilm formation, leading to hospital-associated infections (HAIs). Antibacterial coatings based on natural polymers offer a promising strategy to prevent biofilm establishment while mitigating systemic antibiotic use. However, there are some bottlenecks such as the limited duration of antimicrobial activity and the poor adhesion of the coating to the substrate. In this study, an antibacterial coating with prolonged activity was developed, based on prior work with moxifloxacin-loaded chitosan films. To promote coating adhesion, an approach consisting in wet-chemistry functionalization was studied. PE was treated with piranha solution followed by polydopamine deposition and coated with the moxifloxacin-loaded chitosan formulation. The coatings exhibited uniform coverage; piranha treatment increased roughness and enhanced hydrophilicity, allowing polymer deposition. XPS confirmed successful carbon oxidate species after piranha treatment, and enabled the identification of polydopamine and chitosan, observed by oxygen and nitrogen enrichment. Coating adhesion strength remained stable over 35 days in PBS. Antibiotic release profiles of film and coating were similar, displaying an initial burst (first 10 days) followed by sustained release of moxifloxacin. Antibacterial assay confirmed activity of the coating against
