Cumulative Incidence for the Primary Outcome. The Cox proportional hazard model used to quantify this association is as follows: In(hazard of the primary outcome at time t) = In(1.(t)) + -0.30x1 with x1= 1 for "Intensive Treatment" and 0 for "Standard Treatment" What does the function In(To(1)) estimate in the above Cox regression model? a. The In(hazard of the primary outcome) over the follow-up period for patients randomized to the "Standard Treatment" group b. The In(hazard of the primary outcome) at time = 0 for patients randomized to the "Standard Treatment" group c. The In(hazard of the primary outcome comparing patients randomized to the "Intensive Treatment" group to patients randomized to the "Standard Treatment" group at time = 0 d. The In(hazard of the primary outcome comparing patients randomized to the "Intensive Treatment" group to patients randomized to the "Standard Treatment"
