Logistic regression models using the identified variables from PCA were calculated, and non-significant variables were removed one by one in a descending order. Finally, the above model was reached with nine independently significant variables. The area under the curve statistic was .795, p < .001, 95% CI [.769, .821] which indicates fair-to-good sensitivity/specificity (test values ranged between 0.5 and 1) (n = 1869)
