“…The authors found that attendance at clinic at the later time points (ie, 12 and 24 months) was predicted by asthma, higher computed tomography (CT) score, prior sinus surgery, and recalcitrant subtypes such as aspirin-exacerbated respiratory disease, allergic fungal sinusitis, nasal polyposis, and granulomatosis with polyangiitis.
