John TorousHostFrom the JAMA Network, this is JAMA Psychiatry Author Interviews, conversations with authors exploring the latest clinical research, reviews, and opinions featured in JAMA Psychiatry.

Today, we're thrilled to be discussing a new paper just out in JAMA Psychiatry, GLP-1 Receptor Agonists, Mortality and Cardiovascular Outcomes in Serious Mental Illness.

To find out, we're about to speak with the corresponding author of a new study just published in JAMA Psychiatry that examines outcomes of more than 1.5 million people.
