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

Flavonoids comprise the most common group of plant polyphenols and provide much of the flavor and color to fruits and vegetables. More than 5,000 different flavonoids have been described. The biological activities of flavonoids cover a very broad spectrum, from anticancer and antibacterial activities to inhibition of bone reabsorption and neuroprotection effect. Although emerging evidence suggests that flavonoids have an important role on brain development, little is known about their mechanisms of action. In the present work, we performed a screening of flavonoid actions by analyzing the effects of these substances (hesperidin and rutin) on neural progenitors and neuronal morphogenesis in vitro. We demonstrated that treatment of neural progenitors with the flavonoid hesperidin enhanced neuronal population as revealed by an 80% increase in the number of β-tubulin III cells. This effect was mainly due to modulation of neuronal progenitor survival. Pools of astrocyte and oligodendrocyte progenitors were not affected by hesperidin whereas rutin had no effect on neuronal population. We also demonstrated that the flavonoid hesperidin modulates neuronal cell death by activating MAPK and PI3K pathways. This opens the possibility of using flavonoids for potential new therapeutic strategies for neurodegenerative diseases.
