Participants with CRSwNP have increased nasal cavity clinical scores and report poor quality of life. Compared with healthy participants and those who have recovered from an URTI, CRSwNP report worse nasal cavity complaints (A, B). CRSwNP also report comparatively lower QoL scores (C–I). Kruskal-Wallis test used to identify differences between the mean ranks of at least one pair of the groups. Dunn’s pairwise tests was carried out to identify differences between group pairs. *p < 0.05, **p = < 0.01, ***P < 0.001, ****p < 0.0001.
