1 · What the graph read from it

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.

2 · The registry

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

backgroundDrug-coated balloon (DCB) therapy for in-stent restenosis (ISR) relies on efficient drug transfer during balloon-artery contact. Surface micro-patterning has been proposed to enhance transfer efficiency without altering the antiproliferative drug. This study evaluated a linear micro-patterned DCB (LMDCB) compared with a comparator paclitaxel-coated DCB in a porcine coronary ISR model.

methodsISR was induced by bare-metal stent implantation followed by a 4-week maturation period. In two prespecified cohorts (1 month: 10 animals, 20 segments; 3 months: 4 animals, 8 segments), paired ISR segments within each animal were treated with LMDCB or a comparator paclitaxel-coated DCB (3.0 µg/mm2). Endpoints included quantitative coronary angiography (QCA), optical coherence tomography (OCT), and histology.

resultsAt 1 month, LMDCB demonstrated a larger minimum lumen diameter (2.3 ± 0.2 mm vs 1.9 ± 0.4 mm; p = 0.019) and lower percent diameter stenosis (13.3 ± 4.8% vs 23.7 ± 9.3%; p = 0.003). OCT showed lower mean neointimal thickness (0.2 ± 0.1 mm vs 0.3 ± 0.1 mm; p = 0.008). Histology showed lower neointimal area (2.4 ± 0.7 mm2 vs 2.9 ± 1.1 mm2; p = 0.011) and percent area stenosis (36.6 ± 10.4% vs 44.4 ± 17.8%; p = 0.013), with comparable vascular healing indices. In the independent 3-month cohort, QCA and OCT findings were similar between groups. Exploratory histology in a limited subset suggested a larger lumen and lower percent area stenosis with LMDCB.

conclusionsIn this porcine coronary ISR model, LMDCB was associated with reduced neointimal proliferation and improved luminal dimensions at 1 month compared with a comparator paclitaxel-coated DCB, without impaired vascular healing. In a separate 3-month cohort, imaging findings were comparable between devices, while histology remained exploratory.
