I slightly dislike that his opening paragraphs are wrong. The statement "The group with treatment X had significantly less disease (p = 1%)" does not mean "treatment X it will prevent disease." It only means that there were less disease with a significant probability of being true. IOW, the study might be 99% sure it reduces the disease by 5%.
