摘要: In clinical trials with time to an event endpoint, the Wald test in a Cox regression model may be used assess difference between two treatments. this paper, Bartlett type correction is derived and applied analysis of data from trial on actuate myelogenous leukemia (AML). Monte Carlo simulations are also performed actual I error power proposed corrected test.
