Echoing something in Viliam’s comment, but I think this is looking at the wrong category. It seems like there’s no correlation because Christianity is too broad a category of religions with a common history. Instead, the right comparison seems to be Protestantism vs. not.
Even within Protestantism I think there’s a lot of room for variation. For example, there might be a correlation with certain branches of Protestant Christianity and not with others.
All of this makes it very hard to tell how much was causally the result of Protestant Christianity or even just particular denominations vs. larger cultural forces of which those denominations were downstream.
