35. 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()(t)) + -0.48:1, where x, =1 for females and 0 for males. The standard error of the slope for x, ( SE(B, ) ) is 0.2: What is being estimated by the function In(). (t) ) in this model? a."The In(hazard of mortality) as a function of time (t) in the follow-up period for males in the sample. b. The In(hazard of mortality) when follow-up time =0 for males in the sample c.'The In(hazard of mortality) as a function of time (t) in the follow-up period for females in the sample. d. "The In(hazard of mortality) when follow-up time =0 for males in the sample
