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

purposeTetramethylpyrazine-loaded poloxamer hydrogel materials were studied to achieve the controlled release of tetramethylpyrazine.

methodsFirst, hydrogels having different concentrations of poloxamer 407 and poloxamer 188 were prepared. The gelling temperature and viscosity were measured. Second, we investigated the tetramethylpyrazine release rate from the thermosensitive poloxamer hydrogel materials in vitro and ex vivo. Finally, further study of the pharmacological efficacy of the tetramethylpyrazine-loaded thermosensitive poloxamer hydrogel materials was also investigated in vivo.

resultsThe in vitro, ex vivo and in vivo experimental results showed that the tetramethylpyrazine-loaded poloxamer hydrogel with the appropriate gelling temperature, good adhesion and easy preparation controlled the release of tetramethylpyrazine.

conclusionsThe hydrogel with the suitable nasal temperature and a satisfactory adhesion was selected. The relevant tests were carried out, including the determination of the concentration of drugs in the brain homogenate and the anti-inflammatory test after different modes of administration. So the poloxamer hydrogel was a novel carrier to deliver TMP to pass across the blood brain barrier via nasal administration.
