设疾病在非暴露人群中的发病为P0,则可用下列公式对RR记性校正: RR = OR/((1-P0)+(P0*OR)) 若P0未知,可以用c/(c+d)估计。 SPSS的“交叉表(cross-table)”检验和Logistic回归分析可以直接给出OR值及置信区间。 交叉表检验中,勾选“风险”选项,如图: Logisti回归中,勾选“EXP(B)的CI”选项,如图:...

在logistic模型中,默认状态下 是以因变量取值较小的水平为基 础建模,计算当自 变量取一组特定值时该事件发生 的概率。若想要以取值较大的水平为基础建模 ,则 应在 proclogistic语句之后使用降序(descending) 选项来改变因变量的取值顺序 ,见图2。 第二部分为自变量效应分析 ,筛选自变量的方 法为逐步法,首先将...
