Question
A study assessed two groups of participants who had been treated with different drugs (Drug A and Drug B). The participants were followed for three years and survival was assessed. When plotting the Kaplan-Meier survival curves, the curves for the two drugs diverged after 3 months such that participants who had taken Drug B had a higher survival rate than those who had taken Drug A. However, the survival rates subsequently converged at 24 months and remained the same for the rest of the study period.
Which of the following is a conclusion that can be drawn from the study?
Drug B may offer a better short-term benefit to patients than Drug A.
The frequency of death during the first year was higher for those who took Drug B than those who took Drug A.
Drug B may make patients more susceptible to early mortality.
