Data used for cox proportional hazards analysis

Data sets prepared from lifespan data for use in cox proportional hazards analysis in R. R486 (sometimes listed as R406) denotes presence of RU486 (1) or ethanol (0). When geno term is used, 0 refers to background control and 1 represents presence of transgene (RNAi unless otherwise stated) in file name. GS in file name means lines used had GeneSwitch drivers, while GAL4 means constitutively active driver was used. Time listed is in days, with number of deaths at that timepoint listed in deaths column. Status of 2 used for death, 1 for still living flies. Uro column represents whether uricase RNAi was present (1) or not (0).

本数据集基于寿命数据构建，用于R语言中的Cox比例风险分析（Cox proportional hazards analysis）。其中，R486（有时标注为R406）用于表征样本中RU486的存在情况：取值1代表存在RU486，取值0代表存在乙醇。当文件名中包含基因分型（geno）标识时，0代表背景对照，1代表存在转基因（若无特殊说明，均为RNA干扰（RNAi）型转基因）。文件名中的“GS”表示所用果蝇品系搭载了GeneSwitch驱动系统，而“GAL4”则表示所用驱动系统为组成型激活型。表格中记录的时间单位为天，对应时间点的死亡个体数统计于deaths列中。状态字段取值2代表果蝇死亡，取值1代表果蝇仍存活。Uro列用于表征是否存在尿酸酶RNA干扰：取值1代表存在该RNAi，取值0代表不存在。
