There is no such axiomatic truth. You are making things up and posting medical misinformation. Please provide peer reviewed citations for your claims.
>a repeated event that carries non-zero probability for an adverse effect increases the cumulative probability of said adverse effect when it recurs.
is true by logical necessity. It doesn't need peer-review citation because is it's a synthetic apriori proposition (and also straight out of Probability 101, which unsurprisingly you haven't attended/understood), it's not an empirical claim depending on data.
I would say "learn to read with comprehension" but I fear it's not possible.
>posting medical misinformation

You are making things up without scientific basis.
