[問題] ODDS RATIO及卡方的問題.......
http://myurl.com.tw/ogck 是我要問的問題TABLE3表格,如果太小,煩請各位高手們
下載後放大,感恩。
我看我的PAPER,上面寫著:
As shown in Table 3, pooling the results from these eight studies yielded the
results
(OR=1.27, z=1.88, p =0 .06), which suggests a trend or
significant evidence that the s allele of 5-HTTLPR is associated
with suicide attempts in patients with psychiatric diseases. In the
analysis of the same group of subjects (Table 3), there is a
significant association between the genotypes and suicide attempt
(OR=1.55, z= 2.86, p= .004)。
結論就是都有顯著差異,我好奇說,明明是要算POOLED OR,怎麼又會扯到P值,請問
這個P值怎麼算出來的,我有SPSS這套軟體,能教教我嗎?
但是我又有下載一個軟體
http://www.medcalc.be/manual/meta-oddsratio.php
也是能算出POOLED OR,但是上述網頁提及
The Total Odds ratio with 95% CI is given both for the Fixed effects model
and the Random effects model. If the value 1 is not within the 95% CI, then
the Odds ratio is statistically significant at the 5% level (P<0.05).
也就是若95% CI的OR值若不包含1,才算有顯著標準,才代表觀察操作組與控制組有顯
著差異,是吧?以這個標準來看,TABLE3的ALLELE部分(左邊)有包含1在內,應該是沒
有顯著差異,為什麼文章卻說有呢?到底那一個是對的?
如果有高手了解為什麼,可教我用SPSS算P值嗎?
謝謝
