Actually, a lot of the scientists themselves spoke on it, and people who had first-hand accounts of what they went through. Even a few former members have spoken on what they did. We know the data is effectively worthless for much the same reason as we know Mengele’s data was worthless - the subjects are all sorts of ages and backgrounds and most had been tortured or at least starving in a concentration camp. Data on, say, frostbite affecting HEALTHY people might be worth something, but there are so many confounding factors between disease, starvation, injuries, etc that it’s almost impossible to disentangle the testing data from what was already there.
Additionally, a lot of the data is very obvious shit anyone could’ve told you already, and the experiments (especially with 731) done to make things that looked like science, or experiments that were done to replicate Western science so Japan could internally take credit. It doesn’t take a surgeon to tell you “hey if you put people in a vacuum chamber, they die” or “hey if you vivisect someone and take their lungs out, they need those and they’ll die.”
