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

backgroundTherapeutic options against metallo-β-lactamase producing P. aeruginosa (MBL-PA) are limited due to multi-drug resistance. A jumbo phage isolated from wastewater in Greece was characterized microbiologically and genetically and evaluated for its potential as a therapeutic agent alone or in combination with antibiotics in an experimental thigh infection mouse model.

methodsThe host range of the jumbo phage vB_PaerM_AttikonH10 (AttikonH10) against 20 MBL-PA clinical isolates and 10 susceptible strains, one-step phage growth and growth curves of mid-exponential phase bacteria upon addition of the phage were analyzed. Whole-genome sequencing was performed and the de novo assembled complete phage genome was compared with other jumbo phages. In vivo pharmacokinetics in different tissues as well as the efficacy of two dosing regimens 10

resultsThe phage formed small plaques in double-layer agar and demonstrated clear or semi-clear lysis in 83.3% (25/30) of P. aeruginosa clinical isolates. Growth curves showed a > 94% growth inhibition in the presence of phage even at the lowest multiplicity of infection ratio tested (10

conclusionsThe newly reported Phikzvirus jumbo phage AttikonH10 demonstrated a broad host range, strong lytic activity and synergistic effects with amikacin against MBL-PA isolates making it a candidate for phage therapy.
