在本荟萃分析中，我们研究了婴儿事件相关电位（ERP）研究的特征与其损失率之间的相互关系。149项已发表的研究提供了314个实验组的信息，其中181个提供了损耗数据。随机效应荟萃分析显示，平均流失率高达49.2%。此外，我们使用元回归对178组的减员数据，以分析哪些变量最好地解释减员方差。我们的主要发现是，刺激的性质——视觉、听觉或综合刺激，以及是否有动画刺激——会影响最终分析的排除率，婴儿年龄不会改变损耗率。
In this meta-analysis, we examined interrelationships between characteristics of infant event-related potential (ERP) studies and their attrition rates. One-hundred and forty-nine published studies provided information on 314 experimental groups of which 181 provided data on attrition. A random effects meta-analysis revealed a high average attrition rate of 49.2%. Additionally, we used meta-regression for 178 groups with attrition data to analyze which variables best explained attrition variance. Our main findings were that the nature of the stimuli-visual, auditory, or combined as well as if stimuli were animated-influenced exclusion rates from the final analysis and that infant age did not alter attrition rates.
