I don't read German but I used biological fathers for a reason, does your data include stepfathers? I am familiar with studies like these[0] that indicates a child's lowest risk of abuse is in a household with both biological mother and father, lower even than biological mother alone.

It does, yes, but it doesn't matter. Abuse incidence from teachers and caretakers is ridiculously low, the utter majority of abuse comes from family members and so that is where efforts should be focused.
