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

purposeThe discovery of nano drug delivery system has rendered a great hope for improving cancer therapy. However, there are some inevitable obstacles that constrain its development, such as the physical and biological barriers, the toxicity of carrier materials and the physiological toxicity of drugs. Here, we report a polymeric prodrug micelle (PPM) with pH/redox dual-sensitivity, which was prepared using methoxy poly (ethylene glycol) (mPEG) with favorable biosafety to improve cancer therapy.

methodThe tumor microenvironment stimuli-responsive PPMs were prepared and characterized in vitro and in vivo.

resultsOur data displayed that the PPMs with excellent biocompatibility exhibited the stimuli-responsive drug release behavior under the microenvironment of cancer cells, superior cellular internalization and lower cytotoxicity. A new method to control drug release behavior was proposed by comparing the release behavior of PPMs formed by PEG of different molecular weight. Furthermore, the fabricated PPMs exhibited the "oral-like" blood concentration curve, improved biodistribution, reduced tissue toxicity and excellent antitumor efficiency in vivo. Consistently, these results indicated that PPMs improved chemotherapeutic efficiency and reduced side effects of the model drug doxorubicin (DOX).

conclusionThe prepared pH/redox dual-sensitive PPM enhanced the chemotherapy effect on the tumor site while reducing the physiological toxicity of DOX. Graphical Abstract.
