Neonicotinoid insecticides negatively affect performance measures of non-target terrestrial arthropods: a meta-analysis. Ecological Applications. EAP17-0530.R1

Data presented here was used in Main et al. 2018 to calculate all meta-analytical statistics including standard mean difference, random effects models, and meta-regression models. Data include source of information (e.g., table, figures, in-text), authors, publication year, reported means, SE, sample size, and specific study variables (e.g., study type, active ingredient, organism evaluated, performance measure). See the corresponding metadata for description of variables.<br><br>The metadata provide a detailed description of all variables listed in the master data file. Note: data files for subset analyses (see attached R code) were created (as necessary) from the master data file; however, all information is the same.<br>

本数据集所载数据曾应用于Main等人2018年的研究，用于计算所有元分析统计量，包括标准均数差（standard mean difference）、随机效应模型以及元回归模型（meta-regression models）。数据集涵盖信息来源（如表格、图表、正文中的内容）、作者、发表年份、报告的均数、标准误（standard error）、样本量，以及特定研究变量（如研究类型、活性成分、所评估的生物体、性能指标）。有关变量的详细说明，请参阅对应的元数据（metadata）。

元数据（metadata）将对主数据文件中列出的全部变量进行详细说明。注意：子集分析所用的数据文件（详见附带的R代码）可根据需要从主数据文件生成，但其所含信息与主数据完全一致。
