Elevated E/M ratios were found to associated with worse baseline olfaction and an increased likelihood of achieving a clinically meaningful postoperative improvement in olfaction in this North American population with CRSwNP. Elevated E/M ratios did not predict postoperative changes in SNOT-22 measures or polyp recurrence. This suggests that prognostic factors may vary according to geography and generalized inflammatory profiles (type 2 vs non-type 2) in patients with CRS.
