3.3 L-M CT score and OC score between subgroups of CRSwNP
Compared with B-low subgroup, the OC score was significantly higher in B-high subgroup(P <0.001). For sinus L-M CT scoring, the PES score, ES score, SS score, ES/MS ratio and PES/AES ratio were remarkably higher in B-high subgroup than which in B-low subgroup (P <0.001, =0.002, =0.011, <0.001 and <0.001, respectively) (shown in Figure 2). No significant difference of MS score, AES score, FS score and OMC score between both subgroups was found(P >0.05) (shown in Table E1).
