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

backgroundThe aim of this study was to evaluate the correlation between endothelial nitric oxide synthase (eNOS) polymorphism (-786T>C) and migraine susceptibility in a meta-analysis.

methodsA literature search was performed for case-control studies from inception to July 30, 2018 focusing on eNOS polymorphism (-786T>C) and risk of migraine. From 454 full-text articles, 6 were included in this study. Heterogeneity was assessed with the I index and quality assessment was performed using the Newcastle-Ottawa scale.

resultsCC genotype was not related to higher susceptibility of migraine compared with TT+ TC genotypes with significant difference (fixed effects model; OR = 1.27; 95% CI = 0.90-1.80; P = .17; I = 18%). However, subgroup analysis showed CC variant increase the risk for migraine compared with TT+ TC genotypes in Caucasian populations (fixed effects model; OR = 1.62; 95% CI = 1.03-2.56; P = .04; I = 18%), which could not be observed in non-Caucasian populations (fixed effects model; OR = 0.88; 95% CI = 0.51-1.53; P = .66; I = 0%). There was no significant difference for other genotypes and alleles between patients with migraine and healthy controls (all P > .05).

conclusionThis meta-analysis indicated that CC variant increases the risk for migraine compared with TT + TC genotypes in Caucasian populations.
