Integrating an online weight management program with population health management in primary care: Design, methods, and baseline data from the PROPS randomized controlled trial (Partnerships for Reducing Overweight and Obesity with Patient-centered Strategies)

BACKGROUND Scalable, low-cost weight management strategies are needed in primary care.
