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

Amyloid-β (Aβ) deposit in the parenchyma is a major characteristic in Alzheimer's disease (AD), and the impaired glymphatic clearance contributes to the Aβ accumulation. It was reported that L-3-n-butylphthalide (NBP) showed the potential neuroprotective effect in the rodent models of AD. The effects of NBP on the glymphatic system were explored in this study. In the wild-type mice, both CSF tracer influx and perivascular drainage increased after NBP treatment compared with vehicle treatment. Moreover, NBP promoted the perivascular drainage of Aβ via increased cerebral pulsation, which could be inhibited by propranolol. Then, we studied the potential of 3-month NBP treatment on Aβ deposits in 8-month-old APP/PS1 transgenic mice. NBP daily treatments remarkably improved cognitive behavior in Morris water maze. Furthermore, NBP could reduce Aβ deposition and decrease parenchymal Aβ levels. In addition, NBP markedly improved the perivascular AQP4 localization. Our results indicated that NBP could enhance the glymphatic clearance and reduce parenchymal Aβ deposit in the APP/PS1 mice, suggesting that it may have potential in the treatment of AD.
