The performance of multiple logistic regression model of predicting treatment response status of ITP patients using ROC curve. (A) P-selectin (Base), P-selectin (PMA), PAC-1 (PMA), ROS (PMA), the parameters that were significant at the 0.05 level in univariate analysis and treatment response were subjected to a multiple logistic regression model. (B) The functional assays of the platelet in response to PMA agonist including P-selectin (PMA), PAC-1 (PMA), ROS (PMA), Logit (probability of response) = −20.33 + PAC-1 (PMA)*4.83 + Psel (PMA)*0.673 + ROS (PMA)*0.683; Logit(P) = Log(P/1-P).
