a list of numbers，as follows
　 drug
　 used unused
case 55 128
control 19 164
when use command cci 55 128 19 164 ，i get a odds= 3.708882，95%CI（2.039667，6.941302）
but when use command logit,or
the results like this

logit,or

Logistic regression Number of obs = 366
LR chi2(1) = 22.73
Prob > chi2 = 0.0000
Log likelihood = -242.32729 Pseudo R2 = 0.0448

Note: _cons estimates baseline odds.

the odds is same，but the 95%CI is different，why？
