logistic regression model

hello everyone

still a newbie in statistics...
I made a regression model with binary logistic regression because i have a dichotomous outcome
Now.. I only have 40 cases. Is that enough? Two of the predictive parameters I used seem to be significant but now I don't know whether this is even useful when my group of patients i so relatively small?

Thanks again!
Agreed. Your sample size is ok, considering your field of study IMHO. I've published a fisheries article where I had a logistic curve based on 6 fish. ;)
