Table 2 Khorana Risk Score and Thrombosis Event Correlation. Fisher’s Exact test showed that there is no statistical VTE difference between AML patients with KRS 0 vs. KRS 1–3 (P = 0.2555). Also, a log-rank (Mantel-Cox) test showed no statistical difference of VTE risk between individual subgroups (P = 0.1949)

0 | 191 (22) | 6 (3) |
1 | 445 (51) | 23 (5) |
2 | 207 (24) | 13 (6.3) |
