Phage-Antibiotic Cocktail Rescues Daptomycin and Phage Susceptibility against Daptomycin-Nonsusceptible Enterococcus faecium in a Simulated Endocardial Vegetation
Article in Microbiology spectrum, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers.
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
Enterococcus faecium is a difficult-to-treat pathogen with emerging resistance to most clinically available antibiotics. Daptomycin (DAP) is the standard of care, but even high DAP doses (12 mg/kg body weight/day) failed to eradicate some vancomycin-resistant strains. Combination DAP-ceftaroline (CPT) may increase β-lactam affinity for target penicillin binding proteins (PBP); however, in a simulated endocardial vegetation (SEV) pharmacokinetic/pharmacodynamic (PK/PD) model, DAP-CPT did not achieve therapeutic efficacy against a DAP-nonsusceptible (DNS) vancomycin-resistant E. faecium (VRE) isolate. Phage-antibiotic combinations (PAC) have been proposed for resistant high-inoculum infections. We aimed to identify PAC with maximum bactericidal activity and prevention/reversal of phage and antibiotic resistance in an SEV PK/PD model against DNS isolate R497. Phage-antibiotic synergy (PAS) was evaluated with modified checkerboard MIC and 24-h time-kill analyses (TKA). Human-simulated antibiotic doses of DAP and CPT with phages NV-497 and NV-503-01 were then evaluated in 96-h SEV PK/PD models against R497. Synergistic and bactericidal activity was identified with the PAC of DAP-CPT combined with phage cocktail NV-497-NV-503-01, demonstrating a significant reduction in viability down to 3-log
