[問題] 請問rate ratio 與risk ratio

[derren (我想要ㄉ幸福M)]

有一個橫斷式研究中探討Caffeine Consumption 與Indigestion的關係

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?
請問這個表中的rate ratio是否與risk ratio相同?

謝謝大家!

推 kingbee:口語一點 rate 率  rate ratio 率"比" 也就是兩個率相比
→ kingbee:常用來計算RR或OR
推 kingbee:不過你問的risk ratio 好像在說危險比
推 biostat:那三個rate就指prevalence rates,然後rate ratio就是OR
→ biostat:其中把Low當reference,算出來的!這不是risk ratio
