The gender distribution of thrombotic events revealed insignificant differences according to the type of the events, but the comparison of the cases with controls revealed a significantly higher prevalence of females among the case group (P-value=0.025). None of the comorbid conditions were associated with thrombotic events (P-value>0.05). The patients’ mobility and anticoagulation status were remarkably different between the cases and control (P-value<0.0001). It is also worth noting that all the cases with CVA and arterial thrombosis had not received any form of anticoagulation (P-value<0.001). Detailed information in terms of the comparison between cases and controls is demonstrated in Table 2.
