Five-year outcomes of a drug-coated polymer-free biolimus-eluting stent versus an ultrathin-strut biodegradable-polymer sirolimus-eluting stent.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe biolimus A9-coated polymer-free stent was not non-inferior for target lesion failure (TLF) when compared with an ultrathin-strut biodegradable-polymer sirolimus-eluting stent within 1 year in the Randomized Comparison of a Polymer-Free Biolimus-eluting BIOFREEDOM Stent With a Biodegradable-Polymer Sirolimus-eluting ORSIRO Stent in Patients Treated With Percutaneous Coronary Intervention (SORT OUT IX) trial.
aimsWe aimed to assess the 5-year outcomes of the drug-coated polymer-free biolimus-eluting stent versus an ultrathin-strut biodegradable-polymer sirolimus-eluting stent.
methodsThe SORT OUT IX trial was a registry-based, randomised, all-comer population trial. The primary endpoint, TLF, was defined as the composite of cardiac death, myocardial infarction (MI) not related to any segment other than the target lesion, or target lesion revascularisation (TLR) within 1 year. Follow-up was extended to 5 years.
resultsA total of 3,151 patients were randomly assigned to receive either the polymer-free biolimus-coated stent (1,572 patients [1,966 lesions]) or the ultrathin-strut biodegradable-polymer sirolimus-eluting stent (1,579 patients [1,985 lesions]). Only 0.3% of participants were lost to follow-up, and all of those were due to emigration. At 5 years, TLF was 14.1% in the polymer-free biolimus-coated stent group and 12.0% in the ultrathin-strut biodegradable-polymer sirolimus-eluting stent group (rate ratio [RR] 1.19, 95% confidence interval [CI]: 0.97-1.44). Cardiac death, MI and definite stent thrombosis did not differ between the two groups. Clinically driven TLR was 7.6% versus 5.0% (RR 1.56, 95% CI: 1.17-2.07) and was higher in the polymer-free biolimus-coated stent group at 5 years, attributable to a higher risk of TLR within the first year.
conclusionsFive-year TLF did not differ significantly between the drug-coated biolimus-eluting stent group and the ultrathin-strut biodegradable-polymer stent group, but the risk of TLR was higher in the drug-coated biolimus-eluting stent group.
