Abstract
Background: The DELIVER Clinical Trial was a randomized, single-blinded, parallel-group, multi-center, clinical evaluation of a non-polymeric delivery of paclitaxel -the Achieve TM stent, in the treatment of focal de novo coronary lesions.It was randomized to the stainless Multi-Link Penta TM stent.Objective: Assess angiographic binary restenosis at 240-days in a subset population from the DELIVER Trial.Methods: Between Nov/01 to Mar/02, 1,043 patients were randomized in two groups, implanting either the Achieve TM or ML Penta TM stent, in vessels with 2.5 to 4.0 mm in diameter.From this population, 442 patients completed angiographic follow-up at 8-month.QCA were performed in the postprocedure (PP) and follow-up (FU) angiograms.The angiographic endpoint was 50% decrease in binary restenosis (ABR) at 240-days with the Achieve TM stent.Results: Baseline clinical and angiographic characteristics had no significant difference between the two groups.(pre-procedure RVD was larger in the Achieve TM group).PP and FU angiographic in-stent data are shown in the table below.Quantitative Analyses ACHIEVE n=228 PENTA n=214 p PP Reference Vessel Diameter (RVD) mm 2.99±0.552.96±0.52NS PP Minimum Lumen Diameter (MLD) mm 2.90±0.492.84±0.43NS FU -MLD mm 2.08±0.751.86±0.710.001 Acute Gain -mm 1.91±0.511.91±0.41NS Late Loss -mm 0.81±0.600.98±0.570.003 ABR 14.91% (34/228) 20.56% (44/214) 0.076 % DS 26.08±21.8530.85±22.37 0.024 Predictors of ABR -Multivariate analysis P Odds Ratio 2.5 mm Stent Placed < 0.0001 5.775 [3.125, 10.67] Diabetes Requiring Rx 0.0045 2.244 [1.284, 3.921] IIb/IIIa Inhibitor Use 0.0088 2.321 [1.236, 4.358] Prior MI 0.0472 0.527 [0.280, 0.992] NS=non-significant. Conclusions:The Achieve TM paclitaxel-coated stent treatment arm had a significant decrease in neointimal proliferation compared to the ML Penta TM stent control (late loss 0.81 vs 0.98 mm, respectively, p=0.003), however this reduction was insufficient to meet the pre-specified angiographic endpoint (50% decrease in ABR).The predictors of ABR at 240-days for the subset of patients from the DELIVER Clinical Trial with angiographic follow-up were small vessels (2.5 mm diameter stent implanted), diabetes requiring Rx, use of glycoprotein inhibitor IIb/IIIa and presence of prior MI.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
