When given the question what is the 95% CI for the hazard ratio are you supposed to stop at just the CI or do I have to expoentiate?The HR from the previous is 2.26

42. 1 point Histologic stage is an ordinal categorical variable coded as 1-4 (higher values meaning more advanced progression of disease). Suppose this is initially modeled as a semi continuous variable in a Cox regression, resulting in the following model: In(hazard of mortaility at time t: x)= In(do(1)) + 0.82x1 , where x1 = 1 to 4 for the four histologic stage levels. The standard error of the slope for x1. ( SE(B, ) ) is 0.12. -What is the 95% CI for the hazard ratio from question 41? a. (0.58, 1.06). = 1. 06 CI = 2 82+ 2 (0. 12) b. (-1.06, -0.58) . 82 - 2 (0: 12 ) = 0. 58 c. (1.79, 2.89) d. (0.35, 0.56) e 1. ob 0.58 2. 886 e 1 786 13. 1 poi
