Association between polymorphism and antiepileptic drug resistance in epilepsy: An updated meta-analysis based on 62 studies.

Objective: Previous clinical studies and meta-analyses have shown controversial results on the association between polymorphism of the gene and anti-epileptic drug (AED) resistance. Based on the fact that sample size and confounding factors could contribute to the inconsistency, we performed an updated meta-analysis by including the most recent studies, and subgroup analysis was conducted to evaluate the effect of confounding factors on the association.

Materials And Methods: We searched articles in 6 electronic databases including PubMed, Medline, Embase, Web of science, Cochrane Library, CNKI (China National Knowledge Infrastructure) for relevant articles up to June 2020.
