A retrospective study of drug-coated balloon angioplasty for vertebral artery origin stenosis.
Article in Neuroradiology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
purposeAngioplasty using drug-coated balloon (DCB) for treatment of symptomatic vertebral artery origin stenosis (VAOS) is promising, but of uncertain benefit. This study aimed to evaluate the feasibility, safety, and effectiveness of using DCB in the treatment of severe VAOS.
methodsThis study included 20 patients with severe VAOS treated with DCB alone between April 2018 and December 2019. Vascular death, transient ischemic attack (TIA), and stroke related to the responsible artery within 30 days after procedure were recorded as primary endpoints. Restenosis, late TIA, and stroke related to VAOS and satisfied clinical outcome [modified Rankin Scale (mRS) ≤ 2] were documented at follow-up visit as secondary endpoints.
resultsOf 20 patients, 16 were performed DCB dilation successfully, and 4 were excluded due to further bailout stenting. After the procedure, no adverse event occurred within 30 days. Ten of 16 patients achieved residual VAOS (rVAOS) < 50% (lower rVAOS group), and the remaining 6 patients achieved rVAOS ≥ 50% but < 70% (higher rVAOS group). During follow-up, vertebral artery origin restenosis was detected in 3 (18.8%) of 16 patients by ultrasound. Among the 3 patients with restenosis, 2 were belonged to the higher rVAOS group, which might indicate a tendency that the more severe the residual stenosis, the higher the restenosis rate. All patients had no complaint in the whole follow-up period (median, 7 months; InterQuartile Range, 1-18 months).
conclusionsAngioplasty using DCB for VAOS may be feasible, safe, and effective. The degree of residual stenosis after using DCB alone may affect the restenosis rate.
