To estimate the pooled incidence of epilepsy from published studies and investigate sources of heterogeneity in the estimates.
We searched online databases for incidence studies and used meta-analytic methods to analyze the data.
Thirty-three articles met the entry criteria. The median incidence of epilepsy was 50.4/100,000/year (interquartile range [IQR] 33.6-75.6), while it was 45.0 (IQR 30.3-66.7) for high-income countries and 81.7 (IQR 28.0-239.5) for low- and middle-income countries. Population-based studies had higher incidence estimates than hospital-based studies (p = 0.02) while retrospective study design was associated with lower estimates than prospective studies (p = 0.04).
We provide data that could potentially be used to assess the burden and analyze the trends in incidence of epilepsy. Our results support the need for large population-based incidence studies of epilepsy.
从已发表的研究中估计癫痫的发病情况,并探讨估计值差异的来源。
我们在线数据库中搜索了发病率研究,并使用荟萃分析方法对数据进行了分析。
符合纳入标准的文章有 33 篇。癫痫的中位发病率为 50.4/100,000/年(四分位距 [IQR] 33.6-75.6),高收入国家为 45.0(IQR 30.3-66.7),低收入和中等收入国家为 81.7(IQR 28.0-239.5)。基于人群的研究的发病估计值高于基于医院的研究(p = 0.02),而回顾性研究设计与前瞻性研究相比,估计值较低(p = 0.04)。
我们提供的数据可能被用于评估癫痫的负担和分析其发病趋势。我们的结果支持需要开展大规模的基于人群的癫痫发病率研究。
