标题[问题] 请问rate ratio 与risk ratio
时间Wed Oct 3 22:25:15 2007
有一个横断式研究中探讨Caffeine Consumption 与Indigestion的关系
Table
Prevalence Rates of Indigestion in Low, Medium,and High Caffeine
Consumption Groups, with Rate Ratios (Men)
Caffeine Consumption Rate% Rate Ratio
Low (0 – 150 mg/day)* 33.2 1.0
Medium (151-250 mg/day) 33.0 0.99
High (>250 mg/day) 39.3 1.18
*Reference group
Are the rate ratios in Table risk ratios?
请问这个表中的rate ratio是否与risk ratio相同?
谢谢大家!

1F：推 kingbee:口语一点 rate 率 rate ratio 率"比" 也就是两个率相比 10/04 00:49
2F：→ kingbee:常用来计算RR或OR 10/04 00:50
3F：推 kingbee:不过你问的risk ratio 好像在说危险比 10/04 00:53
4F：推 biostat:那三个rate就指prevalence rates,然後rate ratio就是OR 10/07 01:31
5F：→ biostat:其中把Low当reference,算出来的!这不是risk ratio 10/07 01:32
