I wonder how many of those are from papers discussing failure of peer review or interdisciplinary communication rather than the value of the formula itself.
There are a lot of them that say “using the trapezoidal rule” or something and cite the paper. I think that’s a silly case of unnecessary citations (having been a coauthor on a medical paper there’s a lot of pressure to ‘grab a citation that sort of works’).
But they almost always call it “the trapezoidal rule” - the original paper is quite famous specifically because of the embarrassment it brought to medical researchers, and implication that medicine is full of doofuses who don’t know calculus is pure clickbait.
