*Significantly associated
CORa and AORb were obtained by taking the exponentials of the beta coefficients (i.e., Exp(ß) = odds ratio) together with their corresponding 95% CIs from our univariate and multivariable logistic regression model analysis outputs respectively using SPSS for Windows version 22 to describe the associations between ICS adoption and the possible predictor variables. The AORs (95% CIs) were obtained from one logistic regression analysis model including an outcome variable of ICS adoption and all independent variables simultaneously
