Standardised Warfarin Reversal Expedites Time to Theatre for Fractured Neck of Femur Surgery and Improves Mortality Rates: A Matched Cohort Study

Table 1

Summary of study population demographics for propensity score matched cohorts pre- and post-guidelines. (M: male, F: female, IC: intracapsular, EC: extracapsular; comparing warfarin cases column relates to the warfarin cases pre- and post-guideline; p < 0.05 is statistically significant.)
