Comparison of response rate between the three-pulse high-dose dexamethasone and traditional prednisone regimen groups

Response	PDN (n=36), n (%)	HD-DXM (n=36), n (%)	OR (95% CI)	P†
Initial response*	11 (30.6)	25 (69.4)	5.68 (2.05–15.76)	0.001
Complete response**	3 (8.3)	8 (22.2)	3.05 (0.74–12.62)	0.124
Sustained response***	24 (66.7)	32 (88.9)	4.17 (1.19–14.60)	0.025

*Initial response=Platelet count over 30×109/l after 1 month from treatment; **Complete response=Platelet count over 100×109/l after 1 month from treatment; ***Sustained response=Platelet count over 30×109/l for at least 6 months from treatment; †Significance level calculated from logistic regression with adjusted of other parameters such as age, gender, and bleeding score. PDN=Prednisone; HD-DXM=High-dose dexamethasone; OR=Odds ratio; CI=Confidence interval
