In the FAUST trial, which outcome was reported as a doubling?

• A. Hematoma reduced
• B. First puncture access doubled
• C. Venous puncture reduced
• D. Procedural duration reduced

Answer: (B)

The key idea is interpreting a result described as doubling: it means the rate of a specific outcome in the tested approach is twice that of the comparison. In this trial, the outcome that doubled is the ability to obtain access on the first puncture. First puncture access refers to getting vascular access on the very first attempt, which is highly desirable because it reduces tissue trauma, procedure time, and potential complications. Saying this outcome doubled implies a twofold improvement in initial success with the studied technique or device compared with the control. The other outcomes—reductions in hematoma or venous puncture, or a reduction in procedural duration—would be described as decreases or shorter times, not as a doubling. So the statement that doubled specifically points to the first-pass success rate being twice as high with the intervention, making it the best-supported and most striking reported effect in the FAUST trial.
