Mean INR | Standard error of the mean | Mean difference (95% CI) | Effect estimate (Beta) | Effect standard error | P-value | |
A P-value < 0.05 indicates statistical significance. The interaction effect between thromboembolic, bleeding, minor bleeding, and major bleeding event and time was non-significant (P > 0.05). ICH: intracranial hemorrhage; INR: international normalized ratio; TIA: transient ischemic attack. | ||||||
