The six variables that entered the adjusted Cox's proportional hazard were chosen from those that were statistically significant variables in unadjusted Cox's proportional hazard models.
1When removing ACP from the analysis, the result remained similar.
ACP = antrochoanal polyp; AERD = aspirin‐exacerbated respiratory disease; CI = confidential interval; HR = hazard ratio.
