Obesity is known to create a proinflammatory state in similar chronic inflammatory conditions such as asthma. However, the potential impact of obesity in CRS has not been investigated.</p><p><strong>Methods: </strong>Samples were collected from 512 patients with CRS (235 CRSsNP, 277 CRSwNP) and 100 control patients undergoing surgery in a prospective longitudinal study.
