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
Coronary artery blockage, the most common cardiovascular problem, is often treated with drug-eluting stents (DES). This study aims to address the main limitation of traditional angioplasty therapy. Thus, designing, fabricating, and analyzing a novel drug-eluting polymeric stent using liquid crystal display (LCD) technology may potentially represent an innovative approach to DES in the near future. Therefore, a poly (lactic acid) (PLA) based 3D-printed stent was designed using SolidWorks software and fabricated using the liquid crystal display (LCD) method. The cyclosporine-loaded stent was prepared and analyzed using optical microscopy, differential scanning calorimetry (DSC), and Fourier transform infrared spectroscopy (FTIR). Loading efficiency percentage and release characteristics were estimated. The polymeric stent platform was successfully designed and manufactured using PLA resin. Based on the characterization of cyclosporine eluting stent, a loading efficiency of 48.66 ± 5.92% was estimated through the immersion method. The FTIR and DSC results confirmed molecular interactions between cyclosporine and the PLA-based 3D-printed stent compared with physical mixture formulations. A sustained release profile of cyclosporine was also observed where approximately 50% of the drug was released within the first three hours. The sustained-release profile, characterized by the absence of a burst release, holds significant clinical potential by ensuring consistent therapeutic levels, reducing side effects, and potentially improving patient outcomes. Overall, the study highlights the effectiveness of LCD technology in printing the stent platform using PLA resin. The results demonstrated a significant cyclosporine loading with a sustained release profile without any stent coating procedure.
