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

Sodium channel blocking antiepileptic drugs (SCB-AEDs) are common effective medications available for epilepsy. However, not all patients respond to this regimen and drug resistance is frequently encountered. Rs2298771(c.3184A > G/p.Thr1067Ala) and rs3812718(IVS5N +5G > A) polymorphisms are two of the most common polymorphisms in the SCN1A gene, which is closely related to resistance to SCB-AEDs. Therefore, we have conducted a meta-analysis to investigate the contribution of the two polymorphisms to resistance of SCB-AEDs. The PubMed, Embase, MEDLINE, and Cochrane Library databases were searched up to September 2017, for studies on the association of SCN1A polymorphisms with resistance to SCB-AEDs. A fixed-effects or random-effects model was used to calculate the pooled odds ratios based on the results from the heterogeneity tests. A total of eight studies were eligible for the pooled analysis, of which eight studies included SCN1A rs3812718 polymorphism and four studies included SCN1A rs2298771 polymorphism. The results showed that SCN1A rs2298771 polymorphism was significantly associated with resistance to SCB-AEDs. (A vs. G: OR = 0.76, 95% CI 0.61-0.95, P = 0.02; AA vs. AG + GG: OR = 0.71, 95% CI 0.54-0.94, P = 0.022). However, no association was observed between SCN1A rs3812718 polymorphism and resistance to SCB-AEDs. Our results indicate that the A-allele of SCN1A rs2298771 polymorphism, especially AA genotype, may play an important role in responsiveness to SCB-AEDs, while SCN1A rs3812718 polymorphism is not associated with SCB-AEDs.
