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

Mycobacterium tuberculosis (Mtb) remains a major challenge to global health, made worse by the spread of multi-drug resistance. Currently, the efficacy and safety of treatment is limited by difficulties in achieving and sustaining adequate tissue antibiotic concentrations while limiting systemic drug exposure to tolerable levels. Here we show that nanoparticles generated from a polymer-antibiotic conjugate ('nanobiotics') deliver sustained release of active drug upon hydrolysis in acidic environments, found within Mtb-infected macrophages and granulomas, and can, by encapsulation of a second antibiotic, provide a mechanism of synchronous drug delivery. Nanobiotics are avidly taken up by infected macrophages, enhance killing of intracellular Mtb, and are efficiently delivered to granulomas and extracellular mycobacterial cords in vivo in an infected zebrafish model. We demonstrate that isoniazid (INH)-derived nanobiotics, alone or with additional encapsulation of clofazimine (CFZ), enhance killing of mycobacteria in vitro and in infected zebrafish, supporting the use of nanobiotics for Mtb therapy and indicating that nanoparticles generated from polymer-small molecule conjugates might provide a more general solution to delivering co-ordinated combination chemotherapy.
