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

Intracellular bacteria can multiply inside host cells and manipulate their biology, and the efficacy of traditional antibiotic drug therapy for intracellular bacteria is limited by inadequate drug accumulation. Fighting against these stealthy bacteria has been a long-standing challenge. Here, a system of stimuli-responsive lactoferrin (Lf) nanoparticles is prepared using protein self-assembly technology to deliver broad-spectrum antibiotic rifampicin (Rif) (Rif@Lf NPs) for enhanced infection therapy through targeted elimination of intracellular bacteria. Compared to Rif@BSA NPs, the Rif@Lf NPs can specifically target macrophages infected by bacteria, thus increasing the accumulation of Rif within macrophages. Subsequently, Rif@Lf NPs with positive surface charge further displayed targeted adherence to the bacteria within macrophages and released Rif rapidly in a redox-responsive manner. Combined with the antibacterial activities of Lf and Rif, the Rif@Lf NPs showed broad-spectrum antibiotic abilities to intracellular bacteria and biofilms. As a result, the Rif@Lf NPs with high safety exhibited excellent therapeutic efficacy in the disease models of subcutaneous infection, sepsis, and bacterial keratitis. Taken together, the antibiotic-loaded Lf nanoparticles present a promising platform to combat pathogen infections through targeted elimination of intracellular bacteria.
