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
Lumen-apposing metal stents have expanded the therapeutic potential of interventional endoscopic ultrasound (EUS). The Hot-Spaxus (Taewoong Medical Co., Ltd.), the second most commonly utilized lumen-apposing metal stent, requires two operators for its release which has been considered a limitation compared to other lumen-apposing metal stents. We aimed to test the feasibility and the technical success of a newly available version of the Hot-Spaxus stent equipped with an innovative handle delivery system for EUS-guided interventional procedures. We conducted a pilot study using porcine models. The novel Hot-Spaxus 2 was tested by performing four EUS-guided procedures including four EUS-guided gallbladder drainage and 12 EUS-guided gastrojejunostomy) procedures. Technical success was reported in 100% of cases. The mean procedure time for EUS-guided gatrojejunostomyJ and EUS-guided gallbladder drainage was 23.85 min (standard deviation 3.41) and 16.15 min (standard deviation 2.72), respectively. The distal and proximal flanges were safely released by the endosonographer without any complications. No adverse events were reported. In conclusion, the novel Hot-Spaxus 2 stent may represent an improvement compared to the prior Spaxus model. Unlike its predecessor, this newly designed stent eliminates the need for two endoscopists and can be deployed by a single operator. Further human studies are necessary to validate its clinical effectiveness.
