1 · What the graph read from it

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.

2 · The registry

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: As an important opportunistic pathogen, Materials and Methods: Fifty clinical isolates of Results: A considerable proportion of the clinical isolates showed multidrug-resistant phenotypes, and a considerable number were also classified as extensively drug-resistant. Four lytic bacteriophages, designated HSP1-HSP4, were successfully isolated and purified. All produced clear plaques and reached high titers. Host range analysis showed variable lytic spectra, with HSP1 exhibiting the broadest activity and showing lytic activity against 70% of the tested isolates, followed by HSP2 (58%), HSP3 (48%), and HSP4 (40%). Adsorption analysis indicated that over 80% of phage particles attached to their host cells within 10 minutes, while HSP1 exhibited the highest adsorption efficiency at 93.6%. A short latent period of approximately 20 minutes was observed for all four phages, and burst sizes ranged from 56 to 65 PFU/cell. Transmission electron microscopy revealed isometric heads and contractile tails, morphologically consistent with tailed phages of the class Conclusion: Hospital wastewater can serve as a practical source for the isolation of lytic bacteriophages active against antibiotic-resistant
