Univariate analyses
The variables were entered in univariate logistic regression classifier
to predict revision ESS after baseline ESS. Of the continuous variables,
the highest AUC values were for the number of visits 12, 6, and 3 months
after the baseline visit (AUC = .76, .69, .65, respectively, Table 2).
The next highest AUC values were for the time between baseline visit and
baseline ESS (AUC = .59) and, visit frequency from baseline visit to
baseline ESS (AUC = .59). Of the categorical variables, the highest AUC
values were for CRSwNP (AUC = .65), asthma (AUC = .65), immunodeficiency
or its suspicion (AUC = .61), allergy (AUC = .61) and NERD (AUC = .60).
The coefficients of the continuous variables were positive with one
exception, which indicated that a higher visit number/frequency and, a
shorter time between baseline visit and baseline ESS, increased revision
