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

Klebsiella pneumoniae, a common gut colonizer, has become a major opportunistic pathogen, especially with the rise of multidrug-resistant (MDR) strains. This study aimed to characterize two lytic bacteriophages against MDR K. pneumoniae strains isolated from hospital associated infections in Senegal. Among 28 MDR K. pneumoniae strains tested, phage vKpIN31 effectively lyse 15 strains encompassing 12 distinct K locus types. While phage vKpIN32 lysed 12 strains with 9 different K locus types, demonstrating broad host range activity. The isolated phages exhibited thermal and pH stability. One-step growth analysis revealed a latent period of 25 and 20 min and burst sizes of 281 and 246 PFU/cell for vKpIN31 and vKpIN32 respectively. The in vitro lytic activity of phages vKpIN31 and vKpIN32 at different multiplicity of infection (1, 10
