Reversal of flow during carotid artery stenting: use of the Parodi antiembolism system.
Article in Neuroradiology, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01331473 (PROximal Protection VErsus NON-Protection in Carotid Artery Stenting), which is not on this map. Cited by 3 papers.
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.

Abstract
introductionTo evaluate the flow reversal efficacy of the Parodi antiembolism system (PAES) in the prevention of distal emboli during carotid stenting.
methodsA total of 90 patients were treated for internal carotid artery (ICA) stenosis with a stent device. A PAES device was used in 31 symptomatic and 5 asymptomatic patients (total 36 patients) with ICA stenosis, and 54 patients were stented without any protection device. Diffusion-weighted (DW) imaging was performed before and after stenting.
resultsIn the group without PAES protection, 23 out of 54 patients showed new lesions on DW images after stenting. Of the lesions seen, 147 (2.72 lesions/patient) were in the vessel-dependent area. In the group with protection, 19 out of 36 patients had new lesions, and only 34 (0.94 lesions/patient) were noted in the vessel-dependent area. The number of new lesions in the nondependent vessel area did not differ if a protection system was used (P = 0.671). The use of PAES led to a significant reduction (P = 0.024) in the incidence of the most frequently seen lesions (size <2 mm). The stroke death rate was 3.3% overall, 3.7% in the group without protection device, and 2.7% in the PAES group. There were no permanent neurological deficits after 3 months.
conclusionThe PAES is a safe and effective tool to reduce the incidence of embolic complications during carotid stenting. Older patients and patients with higher grade stenosis seem to profit more.
