The correct answer to the question "When comparing two medical interventions, Treatment A costs $50,000 and adds 2 quality-adjusted life-years (QALYs), while Treatment B costs $75,000 and adds 3 QALYs. Which of the following statements is true regarding their cost-effectiveness?" is Option C: Both treatments have the same cost-effectiveness ratio..

The other options — A) Treatment A is more cost-effective than Treatment B., B) Treatment B is more cost-effective than Treatment A., D) Cost-effectiveness cannot be determined without knowing the incremental cost-effectiveness ratio (ICER). — are incorrect for this USMLE Exam Prep question. As explained above: Cost-effectiveness is calculated as cost per QALY. Treatment A: $50,000 / 2 QALYs = $25,000/QALY. Treatment B: $75,000 / 3 QALYs = $25,000/QALY. Both have the same ratio.
