Applications of machine learning algorithms to predict the incidence of health outcomes have an enormous potential to improve clinical practice and lower health care costs [1].Machine learning is a subset of artificial intelligence that uses data to improve decisions through experience, which is especially promising in a data-driven world.Dr Ye and colleagues' article on hypertension incidence prediction in the Journal of Medical Internet Research adds to this literature [2], but its potential contribution and applicability are hindered by a major flaw.
