How to translate "drew upon"....

Hello,

Could somebody tell me how to translate "drew upon" in the following sentence:

... the experts, who drew upon and ...

Thanks very much

There are so many different ways depending on what you are trying to conclude... try using the verb concluir - los expertos concluyeron que... or you could say "llagaron a la conclusion de..."

Giving more of the context in which it would be used would be helpful...

Thank you very much.
