Table 2.

Showing the p values > 0.05 (without two exceptions as marked) within the two groups in relation to the basic diseases and bleeding events after the Fisher’s exact test. With the Bonferroni correction, the significance level was calculated to p < 0.001 (0.05/42 = 0.001) without any signifincance between the groups and bleeding events in relation to the basic disease
