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

Retinol-binding protein-4 (RBP4) and high-sensitivity C-reactive protein (hs-CRP) levels are associated with inflammation in patients with migraine. The release of proinflammatory cytokines during migraine results in recurrent sterile neurogenic inflammation. This study aimed to determine the correlation between RBP4 and hs-CRP levels, and migraine, which is considered an inflammatory disease. The study included 48 migraine patients and 40 age- and gender-matched controls. Migraine was diagnosed according to International Classification of Headache Disorders-II. The serum RBP4 level was measured using a commercial ELISA kit and hs-CRP was measured using an enzyme immunoassay test kit. The serum RBP4 level was significantly lower in the migraine patients than in the controls (P < 0.001), whereas the hs-CRP level was significantly higher in the migraine patients (P < 0.001). RBP4 and hs-CRP levels did not differ between the migraine patients with and without aura (P > 0.05). Migraine headache severity, frequency and duration were not correlated with serum RBP or hs-CRP levels (P > 0.05). The observed high hs-CRP level and low RBP4 level in migraine patients suggest that vitamin A might play a major role in the pathogenesis of migraine. It is known that inflammation is a key factor in many diseases. Additional research might result in a better understanding of the anti-inflammatory effects of vitamin A.
