Characterization and evaluation of the efficacy of phage E21 therapy in a wound animal model of biofilm-associated Pseudomonas aeruginosa infection.
Article in Scientific reports, 2026. 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
Skin infections caused by strong biofilm Pseudomonas aeruginosa (P. aeruginosa) are considered a serious public health issue because of the increased resistance toward the currently available antibiotics. Consequently, innovative therapeutic strategies have emerged to address these challenging infections. Among them, phage therapy stands out, in which highly potent lytic bacteriophages (phages) are specifically selected to target and eradicate the responsible pathogens. In this study, Pseudomonas phage E21 was recovered from sewage, and it genetically belongs to the Lavrentievirus genus, Casjensviridae family. The genetic characterization of the isolated phage reveals the presence of highly potent lytic enzymes, which play a critical role in effectively suppressing the growth of the targeted pathogens. The phage has high stability patterns over a wide range of temperatures and pH values (65 ℃ and 3-11). Carboxymethylcellulose was used to formulate a hydrogel for the evaluation of the bacteriophage's efficacy against biofilm-associated wound infection in a suitable animal model. The result of the preclinical study confirmed the efficacy of isolated phage in the therapy of biofilm-associated wound infection.
