CRP and transposition of the great arteries: There were no differences in vascular risk factors on admission (systolic and diastolic blood pressure, cholesterol, HbA1c, CRP, CHA2DS2-VASc score) between patient groups (isolated vs. recurrent TGA), as assessed by parametric t-test (in case of normal data distribution: diastolic blood pressure, cholesterol) or Mann–Whitney U-testing (in case of non-normal data distribution: other parameters) (see Table 1).
