　不知道這邊能不能問考古題..不行我再自爆　由於自修沒人可以問,冒昧上來請教大家　這是高醫96年的研究所流行病學考古題 If the risks for subjects exposed to factor A but not B, and exposed to factor B but not A are 6.4 and 4.2, respectively. Subjects with neither exposure to factors A nor to factor B are observed at a risk of 1.8. (a) Using the additive model of interaction, what is the risk for subject exposed to both factors? (b) Using the multiplicative model of interaction, what is the risk for subjects exposed to both factors? (c) If subjects exposed to neither factors have an attributable risk of 0, using the additive model, what is the risk for subjects exposed to both factors? (d) If subjects exposed to neither factors have a relative risk of 1, using the multiplicative model, what is the risk for subjects exposed to both factors? 還望各路高手可以幫忙解答~ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 59.127.159.118 ※ 編輯: hyde7621 來自: 59.127.159.118 (04/16 14:09)
