Assessment of Recurrence Patterns and Treatment Strategies for Reintervention after Paclitaxel-Coated Balloon Angioplasty in Femoropopliteal Artery Diseases: Results of the ASTRA Study.
Article in Journal of atherosclerosis and thrombosis, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
aimsData on recurrence and its patterns after paclitaxel-coated balloon (PCB) angioplasty for femoropopliteal artery disease are limited. We evaluated the incidence and predictors of re-recurrence according to the retreatment strategy (PCB or scaffold) and recurrence pattern (restenosis or reocclusion) in patients with recurrence after primary PCB therapy.
methodsThis multicenter retrospective study included 276 limbs of 246 patients who underwent repeat endovascular therapy (EVT) using either PCB (PCB group, n = 217) or a scaffold (scaffold group, n = 59) for primary PCB recurrence. The primary endpoint was 1-year freedom from re-recurrence, and secondary analyses identified the predictors of re-recurrence.
resultsIn the PCB group, 174 restenotic and 43 reoccluded lesions were treated with PCBs. In the scaffold group, 32 restenotic and 27 reoccluded lesions were treated with scaffolds. In both groups, reoccluded lesions had significantly lower freedom from re-recurrence rates than restenotic lesions (PCB: 43.0% vs. 68.6%, p＜0.001; scaffold: 52.6% vs. 81.5%, p = 0.033). Freedom from re-reocclusion was also significantly lower in reoccluded lesions than in restenotic lesions (PCB: 48.5% vs. 88.6%, p＜0.001; scaffold: 65.8% vs. 93.2%, p = 0.033). The independent predictors of re-recurrence after PCB treatment were male sex (hazard ratio [HR] 2.01, p = 0.010), reoccluded lesions (HR 2.71, p = 0.001), poor BK run-off (HR 1.97, p = 0.020), use of first-generation low-dose PCB (HR 2.32, p = 0.017), and residual stenosis ＞30% (HR 2.60, p = 0.009). After scaffold treatment, reoccluded lesions were also identified as a significant predictor of re-recurrence (HR 2.99, p = 0.043).
conclusionReocclusion after PCB therapy was strongly associated with subsequent re-recurrence, including re-reocclusion, regardless of the retreatment strategy.
