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

Two main contributors of sterile neurogenic inflammation underlying migraine pain, calcitonin gene-related peptide (CGRP), and meningeal mast cells (MMCs) play a key role in the activation of the inflammatory cascade resulting in the sensitization of trigeminal nociceptors. It is well established that phytochemical agent thymoquinone exhibits multiple anti-inflammatory effects in different in vitro and in vivo models of neuroinflammation. But its effects on the CGRP release and meningeal mast cells are unknown. In the present study, we investigated the effects of thymoquinone on the CGRP release in migraine-related strategic structures which are crucial targets for anti-migraine drugs, and on the MMCs in glyceryl trinitrate (GTN)-induced in vivo migraine model as well as in the ex vivo meningeal preparations in rats. Anti-inflammatory thymoquinone ameliorated GTN-stimulated CGRP levels in plasma, and migraine-related structures including trigeminal ganglion and brainstem; moreover, thymoquinone inhibited degranulation of MMCs and prevented the increase in the number of MMCs in GTN-induced in vivo migraine model. However, in the ex vivo meningeal preparations, thymoquinone did not inhibit the GTN-induced CGRP release from trigeminal meningeal afferents. Our findings suggest that thymoquinone mediates modulation of CGRP release in trigeminal ganglion neurons and brainstem, and stabilization of MMCs. Thus, thymoquinone may be a promising candidate to prevent the meningeal neurogenic inflammation and consequently migraine.
