Relationship between sinus symptoms (measured by the Sino Nasal Outcomes Test-22, SNOT22) and asthma symptoms (measured by the ASUI) in participants of different BMI categories. A. Lean participants, linear slope β coefficient = −0.005, SE = 0.0009, p< 0.001, B. Overweight participants, linear slope β coefficient = −0.004, SE = 0.0009, p< 0.001, C. Obese participants, linear slope coefficient = −0.005, SE 0.0008, p< 0.001. Slope of obese group not significantly different than lean group (p=0.475).
