3.4 Correlation analysis and multiple logistic regression
analysis between sinus CT imaging findings and systemic eosinophilia
A positive and weak correlation was found between blood eosinophil count
and PES score, ES score, SS score, ES/MS ratio and PES/AES ratio, but
there was a moderate and positive correlation between OC score and the
level of blood eosinophil count (r=0.57, P <0.001)
(shown in Figure 3). We further determined the independent effects of
PES score, ES score, SS score, ES/MS ratio, PES/AES ratio and OC score
in predicting systemic eosinophilia by logistic regression model, the
above mentioned factors were adjusted for clinical parameters, such as
prior ESS, gender, AR, age and asthma (shown in Table 2). Only OC score
was significantly associated with blood eosinophilia
(P <0.001).
