The presence of hematomas inversely correlated with factor V (r = − 0.5, p = 0.002), factor VII (r = − 0.4, p = 0.003), factor X (r = − 0.56, p = 0.002), and factor XIII (r = − 0.56, p = 0.004), and directly correlated with platelet response to collagen (r = 0.42, p = 0.02) and platelet response to AA (r = 0.44, p = 0.01). This evidence concerns the gene F10 and hematoma.
