d. (1.02, 1.56) - 0.02 0. 94. 39. 0. 98 Recall, the data from the randomized clinical trial of patients with primary biliary cirrhosis (PBC). The Cox PH model that estimares the association between mortality and sex (88% F, 12% M in this patient sample) is : In(hazard of mortaility at time t: x)= In(1.(t)) + -0.48x1 , where x1 =1 for females and 0 for mee in males. The standard error of the slope for x1. ( SE(B,) ) is 0.23. - Suppose other researchers coded x1 as 1 for males, and 0 for females. What would the estimated hazard ratio of death for males compared to females be, and a resulting 95% CI based on this approach to coding sex? HR - 1
