Virtual Reality-Assisted Percutaneous Transluminal Angioplasty for Interventional Treatment of Lower-Extremity Arteriosclerosis Obliterans.
Article in Journal of healthcare engineering, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Cited by 7 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.
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
This study was to evaluate the biomechanical characteristics of the vascular wall during virtual reality- (VR-) assisted percutaneous transluminal angioplasty (PTA) and its effect on the treatment of lower-extremity arteriosclerosis obliterans (LEAO). In this study, a three-dimensional (3D) model and a finite-element model of arteries were constructed first, and various fluid mechanics were analyzed. Then, the virtual expansion simulation (VES) of individualized PTA was performed based on the ABAQUS/Explicit module to analyze the interaction between the balloon and the blood vessel at different times and the changes in the vascular shape and structural stress distribution. Finally, an LEAO animal model was constructed. Based on conventional PTA (PTA group) and VR-assisted PTA (VR-PTA) treatment, the morphological changes of vascular lumen of the two animal models were evaluated. The results showed that the normal, stenotic blood vessels and blood models were successfully constructed; the pressure of the stenotic blood vessel at the stenosis decreased obviously and the shear stress of blood vessel wall increased compared with that of the normal blood vessels, and there may be a blood reflux area in the poststenosis stage. The simulation results of the VES showed that the maximum principal stress value at 3 mm of the marginal vessel was much lower than that at 5 mm (about 10% lower), so the maximum principal stress change within 2 mm of the balloon-expanded vessel was the most obvious. The treatment results of the animal model showed that the VR-PTA group showed an obvious increase in the diameter of the vascular lumen, a decrease in the intima and media area, and a decrease in the thickness of the vessel wall in contrast to the PTA group (
