Figure 3.
Intergroup differences for quantitative parameters. Scatter plots of serum markers for inflammation (WBC, CRP and PCT, a–c), of a marker for cardiac stress (NT-proBNP, (d) and of the vegetation size (measured by transesophageal echocardiography, (e) in patients who underwent operative therapy for IE with confirmed (IE+) or rejected (IE-) diagnoses for IE. (f): Patients with positive (Mort+) vs. negative mortality (Mort-) after 1 year of follow-up. Red dotted lines represent the optimal cut-off values for vegetation size (d) and log(NT-proBNP) (f), comparison of Table 3 and Table 4b. Bars represent the mean ± SD. * p < 0.01, ** p <0.0001, Student’s t-test. Abbreviations as in Table 1.
