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
While the application of a robotic system in neurointerventional procedures has gained notable attention, the current robotic assistance is unsatisfactory. Therefore, we developed a novel robotic system, which was capable of simultaneous coaxial control of three catheters and one guidewire, coupled with rapid-exchange functionality. To evaluate the feasibility of the multi-device robotic system for diagnostic angiography, carotid artery stenting (CAS), vertebral artery (VA) stenting, flow diverter (FD) deployment and aneurysm coiling through preclinical study. The robotic system was tested for feasibility to complete all procedural steps of 5 neurovascular interventions navigating or deploying a variety of common neurovascular devices including the guidewires, catheters, micro-guidewires, microcatheters, coils, the FD, the cerebral protection device and different types of stents. The experimental lateral wall aneurysms were created in 3 live and anesthetized pigs by end-to-side anastomosis using an autologous venous pouch. A total of five surgically created aneurysms were allocated to coiling (n = 2), FD implantation (n = 2) and coiling + FD (n = 1). One VA and one CA were utilized for stenting. All planned procedures were performed successfully with no relevant technical complications or vascular damage. Notably, almost all procedural steps, from different navigation of catheters to device deployment, were completed robotically, with manual intervention limited to radiation-free device exchanges and loading. Robot-assisted operation does not increase the complexity of procedures. This pilot study demonstrates that the multi-device robotic system is feasible for cerebral angiography, navigation of the guiding catheter, aneurysm coiling, FD deployment, VA stenting and CAS.
