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)

Khorana Score	No. (%) of patients, n = 867	No. (%) of thrombosis events
0	191 (22)	6 (3)
1	445 (51)	23 (5)
2	207 (24)	13 (6.3)
3	24 (3)	0 (0)
1, 2, 3, and 4 (all patients)	867 (100)	42 (5)
