Fig. 3. Study III. Thrombin–antithrombin (TAT) complex (A ), prothrombin fragment 1+2 (F1+2) (B ), and β-thromboglobulin (C ) concentrations in native blood (native) and in citrated blood immediately after mixing (T⁰) and after 15 min (T¹⁵), 30 min (T³⁰), 1 h (T¹), 2 h (T²), 4 h (T⁴), and 8 h (T⁸) of storage. *P < 0.05 compared with Native, P < 0.05 compared with T⁰(after Bonferroni correction). P  values indicated relate to overall significance of repeated-measures analysis of variance during storage (T⁰–T⁸).
