PCA models for separating IBS patients and NC. A PCA plot for positive ion model for separating IBS patients and NC. Pre (principal component score) = 10, for X variable dataset, model interpretability R2X = 0.456. B PCA plot for the negative ion model for separating IBS patients and NC. Pre (principal component score) = 8, for X variable dataset, model interpretability R2X = 0.504. C PCA plot for positive ion model for separating active IBS and inactive IBS patients. Pre (principal component score) = 9, for X variable dataset, model interpretability R2X = 0.519. D PCA plot for the negative ion model for separating active IBS and inactive IBS patients. Pre (principal component score) = 7, for X variable dataset, model interpretability R2X = 0.53. IBS 1: Active IBS patients; IBS 2: Inactive IBS patients; NC: normal contral
