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

Migraine causes severe health and social issues worldwide. Rhynchophylline (Rhy) is one of the major active components of Uncaria rhynchophylla that is used for the treatment of headache in Traditional Chinese Medicine. In the current study, the effect of Rhy on nitroglycerin (NTG)-induced migraine was assessed and the associated mechanism was also explored to explain its function. Rats were pre-treated with Rhy of two doses (10 mg/kg and 30 mg/kg) and then subjected to NTG to induce migraine symptoms. Thereafter, the electroencephalogram (EEG) signaling, spontaneous behaviors, levels of indicators related to oxidative stress, and expression of calcitonin gene-related peptide (CGRP) were measured to assess the anti-migraine function of Rhy. Moreover, the activities of MAPK/NF-κB pathway under the administrations of Rhy were also detected. The results showed that NTG induced EEG and behavior disorders in rats, which was associated with the initiation of oxidative stress and increased expression of CGRP. Nevertheless, the pre-treatments with Rhy attenuated the damages induced by NTG by reversing the levels of all the above indicators. The results of western blotting demonstrated that the anti-migraine effect of Rhy was accompanied by the inhibition of MAPK/NF-кB pathway. The findings outlined in the current study revealed an alternative mechanism of Rhy in protecting brain tissues against migraine: the agent exerted its effect by suppressing MAPK/NF-кB pathway, which would ameliorate impairments associated with migraine.
