After backward selection, we identified the combination of PAI-1 together with NLR (HR: 1.056, IC 95%: 1.056–1.093; p = 0.002) (AUC = 0.872; p = 0.004), or t-PA together with NLR (HR: 1.125, IC 95%: 1.125–1.209; p = 0.002) (AUC = 0.906; p = 0.002), as independent risk factors for thrombosis (Figures 3A,B). Here, SERPINE1 is linked to Venous thrombosis.
