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

The antibacterial effects of liposomal vancomycin and teicoplanin against intracellular methicillin-resistant Staphylococcus aureus (MRSA) were evaluated using a macrophage infection model. Human blood-derived monocytes were cultured for 7 days to obtain adherent macrophages. Uptake of each drug by macrophages was markedly enhanced by liposomal encapsulation. Following phagocytosis and removal of residual extracellular MRSA, the infected macrophages were exposed to clinically achievable concentrations of teicoplanin and vancomycin. The free (untrapped) and liposome-entrapped forms of each drug were used at the same concentration. The number of intracellular surviving bacteria was determined by colony counts after lysis of the macrophages at different time intervals following drug treatment. Intracellular antimicrobial effect of each drug was significantly (p < 0.001) increased by entrapment in liposomes. Also, the efficacies of the free and liposomal forms of both drugs were correspondingly comparable (p > 0.05). It is, therefore, concluded that liposomal encapsulation of vancomycin and teicoplanin results in an increased availability of the antibiotics for efficient elimination of intracellular MRSA infection.
