Bioresorbable vascular scaffold versus metallic drug-eluting stent in patients at high risk of restenosis: the COMPARE-ABSORB randomised clinical trial
Bibliographic record
Abstract
AIMS: The aim of this study was to investigate clinical outcomes of patients at high risk of restenosis after implantation of a bioresorbable vascular scaffold (BVS). METHODS AND RESULTS: The COMPARE-ABSORB trial was an investigator-initiated, prospective randomised study. Patients at high risk of restenosis were randomly assigned to receive either a BVS or an everolimus-eluting stent (EES). A dedicated implantation technique was recommended for BVS. The primary endpoint was target lesion failure (TLF), defined as the composite of cardiac death, target vessel myocardial infarction (TVMI) or clinically indicated target lesion revascularisation at one year. The enrolment was discontinued prematurely because of a high thrombosis and TVMI rate in the BVS arm. A total of 1,670 patients were recruited (BVS 848 patients and EES 822 patients). TLF occurred in 43 patients (5.1%) of the BVS group and 34 patients (4.2%) of the EES group (absolute difference 0.9%, 95% confidence interval [CI]: -1.2%-3.0%, p non-inferiority <0.001). Definite or probable device thrombosis (2.0% vs 0.6%, hazard ratio [HR] 3.32, 95% CI: 1.22-8.99, p=0.012) and TVMI (4.0% vs 2.1%, HR 1.96, 95% CI: 1.10-3.51, p=0.02) were significantly higher in the BVS group than in the EES group. CONCLUSIONS: In patients at high risk of restenosis, non-inferiority of BVS compared with EES in terms of TLF was met at one year. BVS carried a higher risk of device thrombosis and TVMI than EES.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
