Although all of these reduce the apnea\u2013hypopnea index (AHI) effectively, the benefits of these treatments have not been thoroughly investigated in a patient\u2010specific manner. Therefore, clinicians do not have objective means to choose an optimal treatment for each patient. We aim to provide clinicians the possibility for treatment optimization in a patient\u2010specific manner by introducing a computational simulation approach. The effect of actual weight change, computationally simulated CPAP treatment and PT and their combinations on the AHI were compared in 54 OSA patients divided into three equally sized groups (weight loss\u00a0&gt;\u00a07%, weight loss 0%\u20137%, and weight gain) after a 5\u2010year follow\u2010up with lifestyle intervention. Weight loss reduced the AHI by 43.5% (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a0.05) and 18%, simulated CPAP treatment with 3.3\u2010hr adherence by 42.4% (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a0.05) and 35.5% (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a0.05), and simulated PT by 13.5% (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a0.05) and 30.7% (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a0.05) in\u00a0&gt;\u00a07% and 0%\u20137% weight loss groups, respectively. Simulated CPAP treatment and PT were able to compensate for the increase in the AHI caused by weight gain. A developed simulation approach could help clinicians to estimate treatment success in advance in order to prescribe the most optimal patient\u2010specific treatment to reduce OSA\u2010related health risks.<\/jats:p>","DOI":"10.1111\/jsr.13070","type":"journal-article","created":{"date-parts":[[2020,6,19]],"date-time":"2020-06-19T01:16:31Z","timestamp":1592529391000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Comparison
