Long-term durability of percutaneous transluminal angioplasty in patients with symptomatic middle cerebral artery stenosis.
Article in Journal of clinical neurology (Seoul, Korea), 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
background and purposePercutaneous transluminal angioplasty (PTA) is being increasingly used in the treatment of symptomatic middle cerebral artery (MCA) stenosis. We evaluated the long-term durability after PTA for symptomatic MCA stenosis.
methodsWe analyzed consecutive patients included in our stroke database who were treated with angioplasty alone. The subjects without major periprocedural complications were followed up for at least 42 months. Recurrent ischemic symptoms were defined as newly developed episodes of transient ischemic attack or ischemic stroke in the territory of the treated vessel. Stroke was defined as ischemic stroke in any vessel.
resultsPTA was technically successful in 37 of the 40 included patients. Thirty-two of the 37 patients were followed up at regular intervals of 1 to 6 months in the outpatient clinic of our institution for at least 42 months. Restenosis occurred in 3 of the 32 patients (9.4%) within 2 years of PTA, and no restenosis was identified thereafter. Two of the three patients with restenosis had asymptomatic complications such as dissection and vasospasm during the intervention. The ischemic area was in the treated vessel in 1 of the 32 patients and in other vessels in 3 of the 32 patients (9.4%).
conclusionsSuccessful PTA can result in a low rate of recurrent ischemic symptoms, and restenosis during a long-term follow-up appears to be more frequent in the early period.
