There were a large number of allegations in the dossier. So, pulling numbers out of the air, but... say it was something like 70% of the allegations were false, 10% were verified true, and 20% could not be verified as either true or false.

As I said, the numbers are made up. But I think the general gist is right - mostly false, a bit true, and some that is unknown.

But this is why people say the dossier was discredited - the majority of it was false.
