Figure 1 legend: During the study period, 300 patients were
referred to the hematology department from the internal medicine
department for IT screening. After exclusion of patients with missing
clinical data, 190 patients were included in the evaluation of the
impact of demographic and clinical characteristics on the risk of
recurrence. Among these 190 patients, 94 patients with complete
thrombophilia screening were appropriately followed up and were included
in the study of the impact of IT screening on the risk of recurrence.
