Bacteriophage cocktails and bacterial coevolution: a systematic review of resistance prevention strategies against multidrug-resistant pathogens in sewage water.

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
Background and Objectives: This systematic review aimed to determine whether phage cocktails and co-evolutionarily trained phages prevent or delay the emergence of resistance in multidrug-resistant (MDR) bacteria more effectively than single-phage therapy in sewage and wastewater-derived systems, and to characterize the underlying mechanisms and the maturity of the current evidence base. Materials and Methods: Following PRISMA guidelines, a systematic review was performed using the PubMed and Scopus databases, with screening conducted via Rayyan Premium. Results: Among 4,795 records, 20 studies (≈0.4%) fulfilled the inclusion criteria; this low fraction reflects a deliberately broad search combined with strict eligibility criteria targeting original experimental studies of phage activity against MDR pathogens specifically isolated from sewage or wastewater. Phage cocktails showed a wider range of host coverage, a delay in resistance development, and improved penetration of biofilms, particularly when paired with depolymerases or antibiotics. Phage co-evolution training resulted in a more prolonged suppression of multidrug-resistant bacteria. Conclusion: Phage cocktails, especially those that are co-evolved and enhanced with enzymes, show potential for applications in wastewater; however, additional long-term and large-scale research is necessary.
