A bit of detail from
Abbott regarding the trial that helped land the approval:

Stent *demonstrated comparable short-term and mid-term outcomes to the leading metallic stent—Abbott’s Xience™ drug eluting stent. At one year in a pre-specified group of approximately 2,000 U.S. patients in the pivotal ABSORB III randomized clinical trial, patients who received the dissolving Absorb
Stent experienced comparable rates of specific adverse events in the intended patient population (reference vessel diameter of >= 2.5 mm and
