An American Journal of Surgery paper used a Markov model to project survival under different weight-management strategies for people with stage 5 chronic kidney disease. Its outcomes are simulated, not observed survival results from a head-to-head patient trial. The projections depend on assumptions, including starting BMI and sustained weight loss. They cannot identify the best treatment for an individual.
