GAS6 and Thrombocytopenia: Patients with thrombocytopenia showed higher median values of both Gas6 (35.6 [25.9–53.8] vs. 30.7 [22.7–41.6] ng/mL; p < 0.001) and sMer (11.4 [6.4–19.2] ng/mL vs. 7.8 [3.1–13.3] ng/mL, p < 0.001) when compared to patients with a normal platelets count (Table S9 and Figure 2a,b).
