However, clinical experience provides approximate equivalencies that help set expectations for where your therapeutic dose may land
Methods A narrative review was conducted by synthesising data from cardiovascular outcome trials, meta-analyses and mechanistic studies involving GLP-1RAs such as semaglutide, liraglutide and dulaglutide
