    I am wondering which preposition should come after "evidence" in the following sentence:

    There is no statistical evidence about / on / of the existence of relationship between the use of the new technique and the type of blood.

    Please advise.

    I would say:
    There is no statistical evidence of the existence of a relationship between the use of the new technique and the type of blood.

    You could say it more briefly:
    There is no statistical evidence of [the existence of] a relationship between the use of the new technique and the [type of blood] blood type.

    (We generally say blood type rather than 'type of blood'.)​
