Number of articles dealing with the efficacy and the durability of GM Bt crops classified according to their topic—durability and efficacy—, their outcome—favorable, neutral or unfavorable to the financial interests of GM crop companies—, and their conflicts of interests (COI)—absence, presence or not determined.本数据集统计了探讨转基因Bt作物（Genetically Modified Bt crops）效力与持久性的相关研究文章的数量，这些文章按以下三类维度进行分类：一是研究主题，即持久性与效力；二是研究结论，即对转基因作物企业的经济利益持支持、中性或反对态度；三是利益冲突（Conflict of Interest, COI）情况，分为无利益冲突、存在利益冲突或未明确三种情形。
