Further blinding details:)

[Guest guest]

Dear Listmates,

Thank you all for your comments. I have now read carefully through

the whole text and I am now more puzzled than before.

It just occured to me that I left out a most important aspect from

my previous message.

The title of the document is:

" A Phase III, Investigator-Blinded, Multicenter, ... "

Later on in the body of the document, it says:

" Neither you nor your doctor will know which of the medications

you receive ... "

Well, I would comment as follows:

1) The title implies that this is a single blind method, but of a rather

curious nature in that it is the investigator who does not know what

drug is being administered, while the patient knows. This would be

quite uncommon as the investigator SHOULD be aware of the

medication taken in order to be able to intervene if necessary.

Anyway, if only one of the sides knows what is actually going on,

then this is a SINGLE-BLIND METHOD

2) The above is contradicted by the statement " Neither you nor

your doctor will know ... " Well, by Jove this means DOUBLE-

BLIND!!!

Any comments?

Thanks in advance.

Regards,

Janos
