quote (carn): 'Sorry, but there seems to be a error, and a realy important one, in counting from this to that:

If the patient doesn't improve, it could also mean, that the treatment had kept him from getting worse. Or the treatment would have caused and improvement, but was countered by a further effect.
And if the patient does improve it could also be due to different reasons, than treatment.'

very good, but it is only an error of omission, or haste, for the correction of which i congratulate you. i do believe you are the first skeptic i've encountered, who could make it as a clinician. (no offense intended )
"The need to perform adjustments for covariates...weakens the findings." BMJ Clinical Evidence: Mental Health, (No. 11), p. 95.... It's that simple, guys: bad numbers make bad science.
