Adjusted Average Inpatient Care Costs for Index Encounter and All Readmissions During 30 Days Postdischarge Between Dabigatran and Warfarin Treatment Groups

Measure	Dabigatran Etexilate Adjusteda Average Value	Warfarin Adjusteda Average Value	Difference (Dabigatran Minus Warfarin)	P Valueb
Index encounter inpatient care costs, $ (n)	9,803 (244)	9,755 (488)	48	0.944
All inpatient care costs from readmissions within 30 days of discharge of index encounter, $ (n)	10,403 (31)	11,911 (72)	-1,507	0.375

^aAdjusted values were estimated using a generalized linear model with gamma distribution, fitted by generalized estimating equations performed using The Comprehensive R Archive Network geepack package.

^bStatistical testing at alpha = 0.05 level. Welch 2 sample t-test for differences in means, assuming unequal variances.
